Original 1st printing 14 x 21&1/4" concert poster for Big Brother & the Holding Company (featuring Janis Joplin) with Iron Butterfly and Booker T. & the MG's at the Fillmore Auditorium and Winterland in San Francisco, CA on 4/11-13/1968. Art by Patrick Lofthouse, image is number 115 in the Bill Graham/Fillmore series. Medium-thick flat index stock poster is in fantastic mint/near mint (A/A- to A-) condition; just one or two miniscule edge/surface dings and that's all; an overall stunning-looking example of this often-underrated Fillmore poster. Portions of these shows were released by Sony Legacy in the late 1990's under the title "Live at Winterland". Arguably one of Big Brother's finest moments on the Winterland stage.
