A spot the difference game with four cards each of three different scenes, complete with instructions/answer sheet and the added bonus of the quality control slip.
Box size: 8 x 6 x 0.75 inches approx. (202mm x 150mm x 20mm).
Showing light wear commensurate with age and storage but overall in particularly nice, clean condition – lovely indeed.
