I recently noticed this excellent set of children's puzzle cards printed in England around 1800 by Benjamin Baker. Each image is engraved and hand-colored and the set retains its original tooled leather case. The cards depict everything from childhood pursuits like badminton, donkey rides, and mock battles, to animals: exotic and domestic, to a large plum pudding.
The images are wonderful as they are both very adult and at the same time intended for children.
The set sold in February at PBA Galleries in San Francisco for $3,250.
