The stamp is part of the United States Postal Service's Black Heritage Series. It recognizes Gibson, the first African American to win a Grand Slam.
Tennis great Billy Jean King was on hand this morning to unveil the stamp on the grounds of the Billy Jean King National Tennis Center in Flushing Meadows.
It also comes on the anniversary of Gibson's debut at the U.S. Open.
After intense lobbying on the part of the American Tennis Association, on August 22, 1950, Gibson was invited to compete in the United States National Championships, now the U.S. Open.
The ATA is the oldest African American sports organization in the U.S. The organization traces its origins back to the late 1800s when historically black universities such as Tuskegee and Howard offered tennis to their students.
However, it wasn't until after the United States Lawn and Tennis Association (now the USTA) barred blacks from participation that the elite among blacks involved in tennis established the ATA.
