Original 1st printing 22 x 14 concert poster for Mike Bloomfield and Chicago Slim appearing with Bola Sete and Mike Finnigan Gold at the Fillmore West from 4/29-5/2/1971, and Ten Years After appearing with Cactus and Pot Liquor at Winterland from 4/30-5/1/1971, all shows held in San Francisco, CA.

 Art by Randy Tuten, image is # 278 in the Bill Graham/Fillmore series. 

 Medium glossy-coated index stock poster is in BEAUTIFUL near mint (A- to A-/B+) condition; aside from a few nearly-invisible soft handling dings here and there, it is pretty much as clean as they come... an overall SUPERB example of this strange-looking late-period Fillmore West poster by Randy Tuten.
