During the Great Depression, businesses would give away glass plates, goblets, and bowls as an incentive to buy, or in some cases, just to come into a theater or store. Today, Depression glass is very collectible, and quality pieces are sometimes hard to find. This two-piece English Depression Cloud Glass bowl, circa 1940, is $239 at James (21 Babbitt Rd, Bedford Hills, 914-514-8981)
