Original 1st printing 14 x 20&1/4" concert poster for the Youngbloods appearing with the Other Half and Mad River at the Avalon Ballroom in San Francisco, CA from 9/15-17/1967. 

 Art by Victor Moscoso with a photo by Paul Kagan, image is # 81 in the Family Dog/Avalon series.

 Medium flat index stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a couple of tiny bends/pressure creases in the corner tips, a soft spot on the "v" of "Avalon", a well-camouflaged hairline crease or two hiding within the image area and a couple of nearly-invisible edge creases, this example is just about as nice as they come. 

 GREAT Moscoso design on this one!
