Decades later, they continue to attract music lovers, and on Saturday, Oct. 22, the niche art will be celebrated during the Festival of Rock Posters at the Hall of Flowers in Golden Gate Park.
The annual event, presented by the Rock Poster Society, is particularly special this year as 2016 marks the 50th anniversary of the invention of the psychedelic rock poster.
“The psychedelic style stood out from everything else in the world,” says poster artist Chuck Sperry, who will have a booth at the festival.
In commemoration of the milestone, posters from the Human Be-In and Summer of Love events will be at the Hall of Flowers, as will two of the artists, Stanley Mouse and Wes Wilson, who will be signing posters for a fee.
In keeping with the psychedelic spirit, the admission fee for the Festival of Rock Posters will decrease as the day goes on.
