Featured is a vintage postcard depicting two bears from Lincoln Zoo, with one bear climbing a ladder to an airship shaped like a Cracker Jack box and the other bear sitting on a tree branch holding a Cracker Jack prize. The scene includes a whimsical poem about the bears flying away in the airship and vowing not to return until the world ate Cracker Jack.
