Depression glass

Depression glass is clear or colored translucent glassware that was distributed free, or at low cost, in the United States and Canada around the time of the Great Depression. Depression glass is a subset of Uranium glass. The Quaker Oats Company, and other food manufacturers and distributors, put a piece of glassware in boxes of food, as an incentive to purchase. Movie theaters and businesses would hand out a piece simply for coming in the door.
