Now an internationally recognized symbol of LGBTQ pride and civil rights, the rainbow flag design was conceived by a group of activists in San Francisco in 1978. Earlier this month, the GLBT Historical Society Museum unveiled a glass case containing a rare artifact: a segment of the original rainbow gay pride flag, its colors as vibrant as ever. GLBT Historical Society / Courtesy of Andrew ShafferĪ priceless piece of queer history has returned home to San Francisco, reports Ezra David Romero for KQED. Queer artist Gilbert Baker preserved this 10- by 28-foot section of an original 1978 pride flag.
