Original 1st printing 11&1/2 x 17&1/2" concert poster for the Grateful Dead appearing at the Pittsburgh (PA) Civic Arena on 7/2/1985.

 Designer unknown/not credited (photo by Herb Greene), medium-thick flat vellum stock poster is in very good (B/B+) condition there is a moderate amount of creasing and a touch of toning along the top/bottom margins, along with a few well-camouflaged stress/handling dings here and there and a bit of corner-tip creasing, otherwise fine.

 Fairly simple mid-'80's GD poster from the 'Burgh. Check out the show HERE:
