Original 1st printing 21&3/4 x 14" concert poster for the Youngbloods appearing with Screamin' Jay Hawkins and Lee Michaels at the Avalon Ballroom in San Francisco, CA from 2/7-9/1969.
Art by Rick Griffin, image is featured in the Art of Rock on page 108 (plate 2.22) and is part of the Soundproof Presents (post-Family Dog Avalon) series.
Medium-thick glossy-coated index stock poster is in very good to excellent (B/B+ to B+) condition; a pair of tack holes in the top left/right corners, a few razor-thin diagonal bends going from the bottom center margin (through the "min" of "Screamin'") going up about 5&1/2" into the snake on the left side, plus and ultra-soft nearly-invisible 3" diagonal bend in the upper left corner, a VERY soft vertical bend on the reverse (it doesn't really show on the front), a couple of stray fingerprints and one or two light handling dings, otherwise fine.
A REALLY nice-looking example of this perennial Griffin favorite from 1969.
