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 excellent (B+) condition; there is a small diagonal bend/crease in the lower left corner tip, along with a few VERY soft/well-camouflaged bends and soft creases hiding within the image area, a "Ben Grandy Company" distributor's stamp and a bit of pencil scratch on the reverse, otherwise fine (the glare on the right side is from sunlight, there is no fading to the color).

 GREAT-LOOKING 1st printing example of this semi-early Family Dog poster.
