This estate sale had a huge collection of concert posters, everything from classic 1960s Bay Area Grateful Dead, Jefferson Airplane, Hendrix to more modern fare, including a lot of Coop, and this fantastic image. Note that Bring Me the Head of Alfredo Garcia is a 1974 Peckinpah film. But for a concert poster, this Frank Kozik artwork is a lot more appropriate.
