This is an original hand-pasted promotional schedule sheet, produced on official Bill Graham Winterland Ballroom letterhead, San Francisco, January 1978. Intended for display at one of Winterland's box offices, it carries two red vinyl stickers bearing the upcoming booking roster for the legendary venue — and what a roster it is.
January 14: Sex Pistols / Avengers / Nuns — the night that would become one of the most consequential moments in rock history. That performance at Bill Graham's Winterland was the Sex Pistols' final show before the band dissolved. The San Francisco Standard It was the biggest concert of the group's career, with the set simultaneously simulcast on KSAN radio, where it would be heard live by thousands of additional listeners and would go on to circulate widely as the most ubiquitous bootleg recording of the group. 
The reverse of this sheet carries four confirmable signatures: Sid Vicious, John Townsend, Jenifer Miro,  And Bill Graham himself — the legendary promoter who built Winterland into the West Coast's premier rock venue and whose personal decision to bring the Sex Pistols to San Francisco helped cement the city's punk legacy.
Graham agreed to the Sex Pistols date after personally calling manager Malcolm McLaren to request the show, Billboard and this sheet is a direct artifact of his curatorial vision. Rather than being discarded after serving its purpose at the box office, this promo sheet became one of Graham's personal gift souvenirs — a distinction that explains both its remarkable survival condition and its extraordinary accumulation of signatures spanning two nights of Winterland history.
