Original 1st printing 21&1/2 x 33&1/2" concert poster for the Grateful Dead appearing with New Riders of the Purple Sage at the East Town Theater in Detroit, MI from 10/23-24/1971.

 Art by Stanley Mouse and Alton Kelley, medium glossy stock poster is in decent/used (B/B- to B-) condition; there is a fairly extensive amount of edge/corner wear on this one (small tears, several loose pin/tack holes, a couple of missing corners), along with a moderate degree of toning/fading to the image, a series of handling/stress creases and tiny pin-prick surface spots/scuffs scattered throughout the image/outer margin area.... definitely a worn survivor, more than likely pulled down from public display at the time of the shows
