Original 1st printing 11&1/4 x 16&1/2" concert poster for the mighty Grateful Dead appearing at Manor Downs Racetrack in Austin, TX on 7/31/1982.
Art by (and SIGNED in pencil in the lower left margin by) Micael Priest, image is featured in the Art of Rock book on page 383 (plate 4.159).
Medium glossy coated index stock poster is in absolutely fantastic mint/near mint to near mint (A/A- to A-) condition; an absolutely STUNNING ARTIST-SIGNED example of this amusing tongue-in-cheek Grateful Dead image.
Check out a nice crisp soundboard recording of the show HERE:
