Great Britain 1840 1d Treasury competition essay by Robert Sievier.
Robert W. Sievier was an engraver, and later a noted sculptor. The one illustrated in this Treasury competition essay shows the central pattern embossed. It was proposed that the engine-turned surround be printed in two or three colours. He believed the stamps printed in such a complicated design in two processes and several colours would be extremely difficult to forge.
A very fine full page example printed in pink and blue with white central embossed motif complete with his promotional narrative outlining his costs. He constructed a printing machine and estimated that he could produce one million impressions per day for as little as £6. 5s.
Originally distributed in stitched copies of the No.65 'London and Westminster Review', and are now extremely scarce in this full page format. Printed on soft off-white wove paper, light and minor wrinkles as usually seen on these spectacular competition essays.
An important piece of postal history regarding the invention of the prepaid adhesive postage stamp.
Accompanied with a 2010 British Philatelic Association (BPA) certificate of authenticity.
