Every illustrator, designer, animator, and artist I know has a collection of these advertising icons. We all grew up watching them on our black and white TV's in the 50's and 60's. They sold us toothpaste, tuna fish and cereal. Charlie the Tuna, Tony the Tiger, Big Boy, Captain Crunch, the Pillsbury Doughboy and many more were turned into lovable objects for us to have. I found many at flea markets and of course eBay.
