I’m in Chicago, visiting the Field Museum, which means two things: Brachiosaurus (see below), and Mold-A-Rama. Downstairs from the great hall, on the ground floor, they have Mold-A-Rama machines, and I cannot resist their siren song. The Mold-A-Rama is the king of novelty souvenirs. You can keep your stamped pennies, little pewter spoons, hand-painted bells, and refrigerator magnets.
