Original 1st printing 13 x 21&7/8" concert poster for the Grateful Dead appearing with the New Riders of the Purple Sage at the UCSB Stadium on the campus of UC Santa Barbara on 5/20/1973.

 Design by Pacific Presentations image is featured in the Art of Rock book on page 369 (plate 4.114). 

 Medium-thick flat vellum stock poster is in very good (B/B+) condition; there are several decent-sized tack holes in each corner, a 1" horizontal tear in the left center margin, a light to moderate amount of toning, a few tiny pin-prick surface spots and a quartet of tape shadows on the reverse, otherwise fine.

 Cool-looking original early-'70's Dead concert poster from a large Southern California outdoor show, stream the soundboard recording HERE:
