Original 1st printing 14&1/4 x 19&3/4" concert poster for the Grateful Dead appearing with Moby Grape and the Steve Miller Blues Band at the Avalon Ballroom in San Francisco, CA from 12/23-24/1966.
Art by (and SIGNED in pencil by) Victor Moscoso, image is # 40 in the Family Dog/Avalon series.
Medium-thick vellum stock poster is in SPARKLING near mint (A- to A-/B+) condition; just a tiny tape-removal pull on the reverse top margin and a couple of ultra-soft handling dings here and there, otherwise it is just about as clean a specimen as you can hope to find.
An absolutely GORGEOUS ARTIST-SIGNED example of one of Moscoso's most enduring Grateful Dead images, perfect for the Holidays!
