Original 1st printing 8&1/2 x 11" concert flyer for the Youngbloods appearing with the Sons of Champlin and Sparrow at the Avalon Ballroom in San Francisco, CA from 12/16-17/1966.
 
 Art by Stanley Mouse and Alton Kelley, image is # 39 in the Family Dog/Avalon series.
 
 Thin flat stock flyer is in very good (B/B+) condition; there are a series of tiny "mouse bite" edge nips along the top right and lower left margins (each about 1-1&1/2" long), along with a semi-soft thin vertical roll bend along the upper left margin and a nearly-invisible handling ding or two hiding within the image area, otherwise fine.

 Virtually all of the conditional issues on this example are limited to the extreme outer margin area, the central image area is VERY clean.
