Original 1st printing 7 x 8&1/4" concert handbill 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 Gilbert Shelton, poster image (by Rick Griffin) 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.
Thin flat stock handbill is in very good to excellent (B/B+ to B+) condition; there is a soft a thin hairline diagonal bend in the upper left corner, a pair of soft surface stains in the upper left margin and in the lower right corner panel, a trace of handling and a VERY soft (mostly visible from the reverse) diagonal bend going from the top center margin down to the lower right edge, otherwise fine.
Very unusual (and not all that easy to find) handbill from the Soundproof Avalon series, this one features a great underground comix-inspired design by the one and only Gilbert Shelton ("Fabulous Furry Freak Brothers", "Wonder Warthog").
