21-Star Historical U.S. Flag

By law a star is added to the U.S. flag on the 4th of July following a state's admission to the Union — this 21-star flag was the official U.S. flag from 1819-1820 (added IL). No U.S. flag ever becomes obsolete, so this remains a fully legal flag to fly today. Appliqued star field with sewn stripes, built for outdoor display.
