Pair of official (promoter-issued) reprint concert posters for a series of shows held at the Avalon Ballroom in San Francisco, CA;
 
 Art by Stanley Mouse and Alton Kelley, images are numbers 31-3 (Daily Flash/Country Joe & the Fish 10/21-22/1966) and 109-2 (Love/Sons of Champlin, 3/8-10/1968) in the Family Dog/Avalon series.
 
 Both posters are on medium flat index stock; the 31-3 is 13&7/8 x 20&3/8" and is in excellent (B+) condition- there are a couple of semi-soft diagonal bends (about 2" long) in the upper left corner and a couple of nearly-invisible handling dings here and there, but overall it is in pretty nice shape; additionally, it is SIGNED in pencil by BOTH Mouse and Kelley.

The 109-2 is 14 x 20" and is also in excellent (B+) condition; there are a few semi-soft handling creases scattered along the left margin, along with a tiny corner-tip bend in the lower left corner and a few stray pinch dings here and there, otherwise fine- no tears/holes/stains, etc. This one has been SIGNED in pencil by Stanley Mouse. 

GREAT-LOOKING ARTIST-SIGNED pair of official 1960's-era FD reprints.
