Mold-A-Rama machines have been popping out plastic souvenirs in and around Chicago for more than 50 years. Based in Brookfield, the machines are located at zoos and museums in five states.

The molds are constantly changing, adjusting to new exhibits at the museums or adapting to a new holiday season. This summer, Mold-A-Rama molds can be found in four area museums: the Field Museum, the Museum of Science & Industry, the Lincoln Park Zoo and Brookfield Zoo, with 26 molds ready to be made.
