June is Lesbian, Gay, Bisexual and Transgender (LGBT) Pride Month, a time to honor the contributions of LGBT individuals in the United States.
LGBT Pride Month is held in June to commemorate the Stonewall uprising, when patrons and supporters at a gay-friendly tavern in New York City led a protest against persecution. The 1969 incident served as a rallying cry for the LGBT community to increase its visibility and efforts to advocate for equality.
The month typically features celebrations of LGBT history, achievements and identities. These activities often include the rainbow flag, a longtime symbol of the LGBT movement.
The Postal Service has honored several gay, lesbian and bisexual Americans with stamps through the years, including artist Ellsworth Kelly, whose works are featured on stamps released May 31; astronaut Sally Ride; and San Francisco elected official Harvey Milk.
