Original 1st printing 14 x 19&7/8" concert poster for the (Steve) Miller Blues Band appearing with Lee Michaels and Congress of Wonders at the Avalon Ballroom in San Francisco, CA from 1/20-21/1967.

 Art by (and SIGNED in pencil by) Victor Moscoso, image is # 44 in the Family Dog/Avalon series.

 Medium-thin flat index stock poster is in ULTRA-crisp near mint (A- to A-/B+) condition; aside from a couple of ultra-soft handling dings, a couple of tiny pin-prick spots in the lower right corner and a VERY subtle/soft diagonal roll bend along the upper left margin/edge, it is an absolutely GORGEOUS ARTIST-SIGNED example of this classic 1967 Moscoso image from the Avalon.
