Another thing I collect is Whitman children's books, games and cardboard tray puzzles from the 1960's and earlier. The attraction, I think, is the colors. They are different than the colors in today's graphics.
I can pick up a book and know that it is 1960's or before sometimes just by the color palette.
Above are my Whitman Animal Rummy cards. The book called My Special Day in the post below is one of my many Whitman books. I still have that one from childhood, but most of them have been thrifted for 10-50 cents each!!
