The first is a rare type of old master print parts of which are decorated with small thin shiny fragments of metal or quartz crystal applied to glue.
Arthur Mayger Hind cites fewer than ten examples as being "practically all whose location is known... all seem to date between about 1430 and 1460".
[3] The second type are popular prints, mainly British, produced in the early or mid-19th century, normally showing actors in their roles, though Napoleon I in his study was another subject.
The theatrical prints cost one penny plain, and two coloured, with a standard size of about 12 by 10 inches (250 x 200 mm).
The artists are not named but the prolific political cartoonist and illustrator George Cruikshank is suspected of being involved.
