Original 1st printing 13&3/4 x 19&7/8" concert poster for the Youngbloods appearing with the Sparrow (an early precursor to Steppenwolf) and the Sons of Champlin 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.

 Medium-thick flat vellum stock poster is in very good (B/B+) condition; there are staple holes in all four corners with a couple of tiny pin-prick surface pulls in one or two of the corners, along with a tiny nip/wedge ttear in the lower right margin, a couple of light tape marks and a bit of irregular toning on the reverse and a series of VERY tiny nips along the top margin, either from the top edge being cut with an irregular blade, or "bug bites"- too small to be from mice, but you can see them. (I put it up against another example I have, less than 1/16th of an inch of the top edge has been compromised).
