Original 1st printing 14&1/2 x 21&5/8 " concert poster, "Independance", a Fourth of July concert featuring Quicksilver Messenger Service appearing with Siegal-Schwall and the Phoenix  at the Avalon Ballroom in San Francisco, CA on 7/4/1967.
 
 Art by Rick Griffin, image is # 69 in the Family Dog/Avalon series.
 
 Medium-thick flat index stock poster is in good (B) condition; the poster is slightly toned, there are tack holes in all four corners, along with a few stray pin-prick surface stains, soft handling bends and tiny creases scattered throughout the poster, plus a few small pressure-crease indentations in the left/right margins and a slight discoloration with a series of tiny pin-prick stains in the lower left corner, otherwise fine.

 A nicely-aged example of this mid-'67 Rick Griffin classic from the Avalon.
