Original 1st printing 17&1/2 x 23" (untrimmed top/bottom margins) concert poster for the Grateful Dead appearing at the University of California Campus Stadium in Santa Barbara, CA on 6/4/1978.

 Art by Maas, image is featured in the Art of Rock book on page 369 (plate 4.113)

 Medium flat vellum stock poster is in excellent (B+) condition; with the exception of a few fairly well-camouflaged soft handling/stress creases hiding within the image area, a couple of tiny dings and a trace of edge toning around the outer margin area and a couple of nearly invisible horizontal roll bends along the lower left margin, it is a FANTASTIC example of this low-run late-'70's Grateful Dead concert poster from Santa Barbara. 

There is also a glossy stock version with smaller top/bottom margins, but this is the first one I have had on flat stock. Check out the show HERE:
