Original 1st printing 8&1/2 x 11" concert flyer for blues legend B.B. King appearing at the University of San Francisco Gymnasium on 6/4/1971. 
 
Design by/printed by Colby Poster of Los Angeles, CA (photographer unknown), thin flat stock letterpress/boxing-style flyer is in near mint to excellent A-/B+ to B+) condition; mostly clean, save for a couple of light pinch bends around the outer margins and a couple of slightly wavy edges, otherwise it is a VERY nice-looking example of this oddball little B.B. King concert artifact from USF
