Original 1st printing 8&1/2 x 11" concert flyer for the Grateful Dead appearing (with the New Riders of the Purple Sage-not listed) at the Bangor (ME) Auditorium on 4/22/1971.

 Designer unknown (photo by Herb Greene), medium-thin flat stock flyer is in absolutely fantastic near mint (A- to A-/B+) condition; just a whisper of surface wear and a tiny pinch bend or two hiding within the image area, otherwise fine.

 An overall fantastic-looking example of this low-run northern New England Grateful Dead flyer from the early-'70's. Check out a GREAT recording of the show HERE:
