Thank you to Yannis Livadas for sending me this photo: Allen Ginsberg, Gregory Corso and George Whitman at the Librarie Shakespeare and Company, Paris. Photo by Francois Lagarde. However, Yannis's eagle eye picked up what the unidentified man on the right is reading ... Sacred Fix by Sinclair Beiles. Date unknown. Sacred Fix was published published by Cold Turkey Press in 1976, and I think Ginsberg still had his beard till the mid-'70s. So maybe late '70s or early '80s?
