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 mint/near mint to near mint (A/A- to A-) condition; there are virtually zero flaws to speak of on this particular specimen- a FANTASTIC example of this low-run regional Dead artifact from one of the band's most fondly-remembered tours (Spring '77).
