Original 1st printing (no yellow border) 28&1/2 x 22&5/8" uncut printer's proof sheet (concert poster and six (6) "Place Stamp Here"-backed postcards) for Canned Heat (Blues Band) appearing with Big Brother & the Holding Company (featuring Janis Joplin) at the Avalon Ballroom in San Francisco, CA from 6/8-11/1967.

 

 Art by Rick Griffin, image ("Magic Show") is # 65 in the Family Dog/Avalon series.

 

 Medium flat index stock sheet is in very good to excellent (B/B+ to B+) condition; a few stray edge nicks and tiny creases, a pair of soft stains in the left margin and bottom center margin, a few scattered stress/handling dings and a fair amount of handling in the upper right corner, but overall it looks pretty sharp.

 

 REALLY NEAT-looking ORIGINAL 1967 1st printing printer's proof featuring one of Griffin's most controversial Family Dog images.
