U.S. Flag Forever Celebrate "Old Glory" with this new patriotic U.S. Flag stamp. The American flag has long symbolized the strength and spirit of our nation. On June 14, 1777, the Continental Congress passed the Flag Act, stating that the U.S. flag should consist of 13 alternating red and white stripes and 13 white stars in a blue field. In 1818, Congress passed legislation stipulating that the number of stars on the American flag should match the number of states in the Union. There are 13 stripes and 50 stars on the current flag. The words "USA FOREVER" are printed on the bottom of the stamp. This listing is for 40 stamps (2 double-sided books of 20) of either the 2016 or 2017 version of the stamp (see images for the two varieties).
