Original 1st printing 14 x 20" concert poster for The Youngbloods appearing with Siegel-Schwall at the Avalon Ballroom in San Francisco, CA from 6/15-18/1967.

 Art by Victor Moscoso, image is # 66 in the Family Dog/Avalon series.

 Medium flat index stock poster is in very good to excellent (B/B+ to B+) condition; there are tack holes in the upper left/right corners, along with a pair of thin horizontal bends and a bit of minor pressure creasing along the left margin, a hint of edge creasing along the right margin and a stray pin-prick indentation ding or two hiding within the image area, otherwise fine. 

 Nice-looking 1st printing example of this always-popular Moscoso Avalon poster.
