Original 1st printing 22 x 17&1/2" concert poster for the Steve Miller Band appearing with John Lee Hooker and Bronze Hog from 3/5-6/1971 and Le Michaels appearing with Joy of Cooking and the Fourth Way from 3/12-13/1971, all shows held at Pepperland in San Rafael, CA.

 Art by Mark T. Behrens, medium-thick glossy-coated index stock poster is in very good to excellent (B/B+ to B+) condition; there is a small area of moisture wear/creasing and a few tiny rub marks in the lower left corner, along with a bit of light surface wear (a few light scuffs hiding within the image area), a few stray soft handling dings here and there, a bit of light foxing/pin-prick age spotting around the outer margin area and a couple of minor stains on the reverse side, otherwise fine. 

 Very strange-looking early-'71 concert poster from the legendary Marin County venue. Check out a great history of the building that housed Pepperland HERE:
