Original 1st printing 8&1/2 x 11" concert flyer for the Grateful Dead appearing at the Baltimore (MD) Civic Center on 5/26/1977. 

Art by C. Regan/Grateful Graphics, thin flat stock flyer is in near mint (A-) condition; with the exception of a nearly-invisible pinch ding or two hiding within the image area, there are virtually no flaws to speak of... a SUPERB example of this low-run regional Dead artifact from one of the band's  hottest late-'70's shows  from the legendary Spring '77 run.

 Check out the soundboard recording of the show HERE:
