Great Americans series

The Great Americans series is a set of definitive stamps issued by the United States Postal Service, starting on December 27, 1980, with the 19¢ stamp depicting Sequoyah, and continuing through 1999, the final stamp being the 55¢ Justin S. Morrill self-adhesive stamp. The series, noted for its simplicity and elegance, is a favorite of stamp collectors. It was replaced by the Distinguished Americans series, which began in 2000.
