Unlike the hand press used for the stamps where the imagewas printed from a plate with recessed impressions, the plateused for the steam press required a raised or relief impression. This allowed the plate to be inked by passing under a rollerbefore having the paper rolled over the plate via the cylinderthus allowing the whole process to be combined into oneoperation. The plates or formes were created from twelveidentical stereotype plates cast in an amalgam of lead, zinc andantimony – and they were cast from plaster of Paris mouldswhich were all taken from one original plate.of one or two shil lings depending on the denominations)were required for each forme. The size and complexity ofthe design meant that each of the stereotypes requiredcorrection. On Ap ril 10th Henry Cole wrote to JohnThompson “Mr. H ill is desirous that, without delay youexamine the ster eotypes which have been taken from thebrass plate and t o do whatever is requisite in order that theymay be ready for the press on Monday [13th].”. On MondayApril 13th Rowlan d Hill called on Thompson to pick up 36plates only to fin d that 24 had already been returned to theprinters. On that day Hill also made the last addition to thestereotypes by in cluding a unique “A” number between 1and 210. These a ppear randomly on the formes althoughthe omission of c ertain numbers suggest several of thestereotypes were unusable. Eight presses were put intooperation during the first week of printing that actuallybegan on Tuesda y April 14th indicating that 96 individualstereotypes had been produced.The plate was made by John Thompson (1785–1866), thepre-eminent wood engraver of the day, who was charged withcutting the image in relief on brass. This must have provedsomewhat difficult as Hill did not receive a finished proof fromthe brass plate until April 1st. Numerous proofs do exist fromthe brass plate in various stages of completion however itwas not until the discovery of the Wallace correspondencethat a stereotype proof dated March 15th 1840 proved thatthe design must have been substantially complete by thesecond week of March. The taking of these first stereotypeshighlighted the weakness of the background design and ledto an overall strengthening of the lines, not an easy task whendealing with a relief engraving. The early stereotypes did allowfor at least one forme to be produced for comparative essaysof the side tablets that were to accompany the design, theearliest of these dating from March 20th.A letter from Henr y Cole to William Mulready on April 15thcontaining a 2d. le tter sheet overprinted “PROOF” reads “Mydear sir, Here are specimens of the real thing now printingat the rate of seve nty thousand per hour.”. A similar proof inthe Wallace archiv e may well be the adjoining stereotype andwas presented to him by Francis Baring on the same day. Ofthe eight presses, four were for 1d. lettersheets, two were for1d. envelopes, and one each were for the 2d. stationeryEachsheet took approx imately five seconds to produce comparedwith a minute and a half for every sheet of the stamps. On April 3rd Francis Baring sent a copy of the finished proofto Queen Victoria with a memorandum from Mulready andThompson explaining the design. On Monday 6th Hill’sdiary notes “Met Thompson Pressley and E.H. [Edwin Hillhad been appointed to supervise the manufacture of thestamps etc at Clowes’s] to superintend the arrangement ofthe several parts of the covers and envelope stamps. LeftClowes’s people taking stereotype casts under direction ofE.H.”. This and several surviving proofs annotated by Hillconfirm this as the date the design of the side tablets wereapproved. Stereotype production continued all week and, onThursday 9th, Hill confided in writing in his diary the pressureand time constraints he was working under: “E.H. is makinggreat exertion, he is at Clowes from 6 in the morning till 10 atnight. They seem to think at the Stamp Office that the wholemachinery is to be set to work without any trouble on theirpart.”. On April 10th Hill took copies of the proof taken fromthe brass plate to the National Gallery.THE WALLACE C ORRESPONDENCEThe Wallace corre spondence was originally contained ina binder belongin g to Robert Wallace. It had passed fromWallace to the Cal dwell family in Scotland and they haddisplayed various parts of the collection at local philatelicsocieties through out the years. In 1991 it was consigned toCavendish Philate lic Auctions who sold it to an overseas buyerin its entirety. It w as then broken up and the three major pieceswere separated. I n chronological order: the earliest known1d. Mulready stere otype proof a91 presented to Wallace byRowland Hill on M arch 15th; secondly, the April 10th documentpresented here; a nd thirdly, a 2d. Mulready letter sheet datedApril 15th, fresh o ff the steam presses at Clowes, that had alsobeen presented b y Francis Baring. This latter was the bottomAtright-hand copy fr om the sheet of twelve, with the stereonumber A99.APRIL 10, 1840 The security paper for the issued stationery came fromJohn Dickinson and Sons based in Hertfordshire. His silk-thread paper involved embedding lines of colored silk in acontinuous web of machine-made paper while still in the pulpstage. The idea had been inspired by the government rope ofthe day, as intertwined in the braid was one white strand todenote its official status. The paper was prepared at ApsleyMill near Rickmansworth and it appears that it was favouredfor the stationery from very early on. An early essay for theLondon District Penny Post in 1837 had featured the paperand had been widely circulated gaining particular praise forits protection against forgery. Even though the contract forthe supply was opened to public tender in January 1840 thecontract was awarded to Dickinson at the beginning of March.On the morning of Friday April 10th, 1840 Rowland Hill madeFrancis the three-mile journey from his residence at 1 Orme Square inBayswater to his office at 11 Downing Street. It was nearly theend of a very busy week. The previous Friday April 3rd, QueenVictoria had declared herself “much pleased” with the designby William Mulready for the envelopes and wrappers. OnMonday he had been able to finalize the inscriptions that wereto accompany the design with William Clowes and Son, theprinters, and John Thompson, the engraver. The first plate forthe new Postage Stamps had been completed on WednesdayApril 8th by the engravers at Perkins, Bacon & Petch andwas set to begin printing only for the want of the first reamsof the new crown watermark paper. The presses at bothestablishments were being prepared and, hopefully, full-scaleproduction would begin the following week. Both the public andthe Government were growing impatient for the appearanceof these new methods of prepaying the mail that had beenpromised for March yet until this day only a very select few hadseen the actual designs.time Hill, a famed early riser, leaving for work,Baring, Chancellor of Exchequer, and RobertWallace, M.P. were preparing to go to bed.The three-daydebate on the motion against the Whig government on thequestion of the Opium Wars with China had been defeatedby a majority of a mere nine votes at 4:30 a.m. that morning. Both had voted against, in support of the government,following the marathon twelve-and-a-half-hour session ofParliament.The identically ma rked Mulready, likely the adjoining copy, whichwould have been t he second removed, was sent to WilliamMulready and is no w housed in the British Postal Museum. It is possible that this was when the notations on the Wallacedocument were w ritten. The note at the bottom of thedocument states “These come into public use on the 6th ofMay”. Rowland Hi ll had visited both printers the previousday (April 14th) w ith the intention of fixing the date for theintroduction of th e new stamps and notice of a pending officialannouncement w as made the following day in The Times. Wallace must hav e made a special allowance for this visit toDowning Street as he would have had to leave London onthat day in order t o return to Scotland in time for Easter, thejourney then takin g three days by rail and stagecoach. He didnot attend that af ternoon’s closing session of Parliament.It was almost certainly Francis Baring who advised Hill to visitthe Royal Academy who were met “in council” at the NationalGallery, as the approval for the Mulready by the Council ofRoyal Academicians was regarded as essential. It was Baringwho, through Henry Cole, had suggested Mulready as theartist for the new postal stationery. Baring’s family had a longhistory of patronage of the Royal Academy and, as such, hemay well have intended to attend the meeting. Unfortunately,the House of Commons was in session and the affairs of Statetook precedence.Production of the finished stereotype plates of the Mulreadybegan on April 6th 1840.
