Sam and Dave / James Cotton Blues Band, Country Joe and the Fish / Loading Zone at the Fillmore Auditorium, San Francisco July 18-23, 1967. Original poster printed only once, before the concert. Listed in Eric King’s Collector’s Guide as BG-73-OP-1. Size 14″ x 21″. Matte finish on index stock. Fine condition overall, but I smashed the edge accidentally, causing a 1 1/2″ x 3″ triangular crease on the left edge. The colors are deep and rich and the paper is white. This has been stored rolled for decades. Thanks for your interest!
