Original 1st printing 19 x 28&1/2" concert poster for the Grateful Dead with special guests the New Riders of the Purple Sage and the Blues Brothers at Winterland in San Francisco, CA on 12/31/1978 (the FINAL Winterland show). Art by Stanley Mouse (who also SIGNED the poster in gold ink) and Alton Kelley, image is featured in the Art of Rock book on page 343 (plate 4.38). Medium-thick glossy-coated index stock poster is in fantastic mint/near mint to near mint (A/A- to A-) condition; perhaps there's a tiny corner bump or stray fingerprint, but it's basically as crisp/sharp as they come. A GORGEOUS-looking SIGNED example of one of the most famous Dead images of all time. You can stream the show HERE:
