Original 1st printing 14&1/8 x 17&3/4" concert poster for Big Brother & the Holding Company (featuring Janis Joplin) appearing with Lee Michaels and the Oxford Circle at the Avalon Ballroom in San Francisco, CA from 12/9-10/1966.
Art by (and SIGNED in black pen by) Victor Moscoso, image is # 38 in the Family Dog/Avalon series.
Medium-thick flat vellum stock poster has been partially restored to very good to excellent (B/B+ to B+) condition; there are a series of ultra-tiny pin-prick holes in each of the four corners that have been closed up/painted over (a few of them with what looks like white-out), plus a few additional VERY hard-to-see pin holes hiding within the image area and one in the bottom left corner tip, a thin 3" diagonal bend in the upper left corner, a couple of nearly-invisible surface stains, a hint of handling/surface wear and a bit of pencil scratch on the reverse, otherwise fine.
EXTRA-BRIGHT colors on this example, not to mention the HUGE Moscoso signature (see photo). One of the most oft-requested images in the Avalon series.
