Barnum’s Animal Crackers, a long time snack for generations of kids, hasn’t changed much in terms of package design. The simple box depicted caged animals transported in a rail car, which, when the crackers were first introduced to market, was how circuses toured from town to town.

But a lot of things about the circus has changed, including the shuttering of “The Greatest Show on Earth” in 2017 following declining ticket sales, an indicator of changing attitudes towards the big top amid reports of animal mistreatment and poor conditions.
