I was absolutely obsessed with this toy when I was a kid. What kills me about shopping at my local dump’s “gift hut” is that so many of the local and elderly residents dump off the best vintage toys sometimes. I think that they clean out those basements and are finally getting rid of their grown kids toys. I ordered this every year from the Sears catalog.
What one would do is open the hat that Mickey is holding, it acts like a little door. You put the colorform thingie in there, turn the wheel and each little colorform piece reveals a secret or another pic than what is on the actual colorform.
Every colorform piece is still here. Lots of good ones here.
