This mischievous-looking bear dates from the mid-1940s, when plastics, wood and Lucite were creatively used during WWII to make up for the metal shortage. Measuring 3" high, he is made from cinnabar-red molded plastic, with over-painting and shellacking. He has a metal pin stem with a plastic "C" clasp. Excellent condition.
This is one of the few plastic pins I've ever seen to carry a design patent. There are four pins in this series, each with its own design patent: this bear, two dogs (see item B11058), and an elephant. The designer was Nicholas Barbieri, an apparently prolific designer for Uncas, judging by the number of design patents awarded to him.
