Peanut Butter Glasses
Sometimes it's not about the peanut butter or the jelly, but the containers they've arrived in—glasses printed with illustrations of flowers, animals, trains, cartoon characters, and all sorts of other cultural touchstones. Barbara E. Mauzy is both a collector and seller of them, and her 2002 book Peanut Butter Glasses is apparently the definitive guide to these collectibles, featuring almost 1100 photographs and notes.
Karen's Peanut Butter Glasses is a small but great catalog of tumblers from the 1950s, arranged by category; the fruits are my favorite, although the dogs are pretty great too! If you're looking to buy one (maybe a glass you remember from your childhood?) eBay has a hundred or so for sale right now, many for less than $5.
