Original 1st printing 18&1/2 x 14&1/8" concert poster for the Sons of Champlin appearing with the Elvin Bishop Group at the College of the Desert in Palm Desert, CA on 10/12/1974.
 
 Design by Bast, medium-thick glossy-coated index stock poster is in very good to excellent (B/B+ to B+) condition; there are a few light handling dings, a bit of light surface wear and a pair of very soft vertical bends along the left margin, along with a thin vertical crease in the bottom center margin, a couple of nearly-invisible surface stains in the left-side panel and in the lower left margin, a long tape pull along the reverse right margin and a trace of moisture warping on the left side of the poster, otherwise fine.

 Really nice design on this one, the first example I have ever had for sale.
