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 (B/B+) condition; there are a few light handling dings here and there, along with a couple of tiny surface pulls along the left border of the artwork, a moderate amount of light/soft moisture splatter in the lower right margin/corner and a slight amount of rippling to the paper, otherwise fine.

 Really nice design on this one, only the second example I have had for sale.
