Issued for the U.S. Bicentennial, this comprehensive stamp set was a forerunner of the popular U.S. 1999-2008 Statehood quarter series. All state flags are represented on these colorful stamps, in the sequence of each state's admission to the union (Delaware to Hawaii, just like the later quarter series, but issued all in one year). They come in beautiful original quality joined together in this official mint sheet. The set makes a great gift and is the perfect accompaniment to any Statehood quarter collection.
