Original 1st printing 14 x 21" concert poster for the Grateful Dead appearing at the University of Nevada Reno Football Field on 5/12/1974. Designer unknown, thin flat vellum stock poster is in absolutely stunning mint to mint/near mint (A/A- to A-) condition; just a tiny ding in the bottom right corner, a trace of handling wear and a hint of foxing/spotting on the reverse, otherwise a fine example of a MEGA-SCARCE low-run regional Dead poster from an early "Wall of Sound" show, check out the show HERE:
