1920 Pilgrim Tercent. #548-550

1920 Pilgrim Tercentenary #548-550
A set of three stamps noted the 300th anniversary of the arrival of the Pilgrims in Plymouth, Massachusetts. These old American stamp designs show the Mayflower, the landing at Plymouth Rock and the signing of the Mayflower Compact. They also represent the first time in U.S. postal history that the words "United States" or "U.S. Postage" failed to appear on a stamp.
