Original 1st printing 11 x 17" concert poster for 1970's FM-rockers Boston appearing with Eddie Money and Sammy Hagar at the Silverdome in Pontiac, MI on 8/19/1978.

 Art by (and SIGNED in black pen by) Gary Grimshaw, thick flat vellum stock poster is in BEAUTIFUL near mint to excellent (A-/B+ to B+) condition; aside from a VERY small soft diagonal bend in the top left corner tip, a thin hairline bend in the lower left margin, a tiny edge ding or two and a soft pull on the reverse, it is in SUPERB shape.

 GREAT-looking ARTIST-SIGNED late-'70's Grimshaw poster from Michigan.
