Original 1st printing 14 x 19" concert poster for Quicksilver Messenger Service appearing with Ace of Cups and the Flamin' Groovies at the Avalon Ballroom in San Francisco, CA from 5/10-12/1968.

 Art by Raphael (Bob) Schnepf, image is # 118 in the Family Dog/Avalon series.

 Medium-thin flat index stock poster is in near mint to excellent (A-/B+ to B+) condition; there are a couple of tiny bends and light handling creases along the lower left margin, along with a couple of small pressure creases along the left margin and a soft handling ding or two hiding within the image area, otherwise it is a SUPERB example of this amusing mid-1968 Avalon poster.
