Check out The Candy Wrapper Museum, where delicious sugary ephemera lives on.
My personal favorite: Fruit Cocktail Imperials. Check out the snazzy martini glass! Also deliciously mid-century modern: Cool It! I've always had a secret fondness for Ferrara-Pan candies--who can resist Atomic Fireballs and Lemonheads? And who would not want to enjoy a delicious Pet Rabbit or a Cat Tongue?
The Candy Wrapper Museum is not comprehensive tho'. Their collection seems to be lacking wrappers for jacksnaps, crumbly-crumb-o's, and jiffy-ju's, and, of course, Tiny Doom's favourite (not!) choco-sniffs.
