Jewel-like in its size, this photogravure is one of the finest that Talbot accomplished and would not be out of place in a well-printed publication today. How many prints of this quality Talbot could produce is uncertain; the only other known copy of this is in a special album compiled by Talbot, Gravure Photoglyphiques now at the National Media Museum. The fine grain here is 'wormy' in structure (rather than being like sand), almost certainly indicating the use of a solvent-based resin to lay the aquatint ground.
