How about those cool plastic Dinosaurs in Wheat Honeys and Rice Honeys?
I once sent away Cheerios box tops and 25 cents and got a Harlem Globetrotters Nerf Basketball!
I also sent away five wrappers from the Marvel Comics gag stickers (around 1967) and got an authentic shrunken head... Made of authentic plastic!
I was SO disappointed.
Remember when Hank passed Willie, on his way to passing the Babe, in the career home run chase?
