These would have been used to play Happy Families, in sets of 4. What I find particularly interesting is the original artist visualised the book so differently from Disney... but of course, he would have seen the original Barrie play.
As always, left-click for the full size picture, then right-click to Save As into your My Pictures folder. Do whatever you like with them (including items for sale) as long as you don't use them for commercial collage sheets or CD collections.
Aren't they good fun!
