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 is in decent (B/B-) condition; this one has a bit of toning, tape residue marks in the corners and on the reverse, a bit of curl to the paper with a few ultra-soft horizontal roll bends, light handling wear, a few stray thin creases here and there, a light moisture stain in the top margin and tape pulls/stains on the reverse (as well as a "Lorin Gilette Distributor" stamp in the bottom center margin), otherwise fine.

 

 A very charming slightly-used 1st printing example of this perennially popular Family Dog image.
