The U.S. Bicentennial lithograph stamp sheets are a series of celebrations during the mid-1970s that commemorated the historic events leading to America’s independence from Great Britain. The official events began on April 1, 1975, when the American Freedom Train departed Delaware to begin a 21-month, 25,338-mile tour of the 48 contiguous states. For more than a year, a wave of patriotism swept the nation as elaborate firework displays lit up skies across the U.S., an international fleet of tall-mast sailing ships gathered in New York City and Boston, and Queen Elizabeth made a state visit. The celebration culminated on July 4, 1976, with the 200th anniversary of the adoption of the Declaration of Independence.

The stamp sheets measure 6”H x 8”W and are a "must have" for stamp collectors and enthusiasts. The sheets are new in mint condition.
