Parrot depression glass was made by the Federal Glass Company between 1931 and 1932. Parrot was made in green and amber. The amber pieces have sky rocketed in value in the past few years. Hot plates have been very strong in value. Very few green 80 ounce pitchers are known to exist and the values are in the thousands of dollars if you are lucky enough to find one. The more common plates and bowls are more affordable for the collector who is just starting out.
