what was the first year the american flag was the sole feature on a stamp
United States Flags on United States Stamps. The first United States stamp to show the U. S. flag-four of them-was issued in 1869. It is Scott 121, the 30Â¢ of the set, and the Flags shared the small space (21mm X 21mm) with a shield and an eagle. The flag is printed in blue. A flag stamp doesnât appear in multicolor until 88 years later, in 1957.
