Original 1st printing 13 x 16&1/2" concert poster for the "New Age Biocentennial Unity Fair", a free show featuring the Grateful Dead appearing with Jefferson Starship at LKindley Meadows in Golden Gate Park in San Francisco, CA on 9/28/1975.
Artist unknown/not credited, medium textured semi-gloss stock poster is in near mint (A-/B+) condition; just a few light handling/edge dings and a hint of surface wear, otherwise fine. The reverse of the poster has a fairly heavy ghost image (see photo).
VERY COOL and unusual low-run oddball Grateful Dead poster from one of only FOUR performances by the full band in 1975. Listen to the Dead's set (featuring a lot of then-brand-new "Blues for Allah" material) HERE:
