Original 1st printing 10&3/4 x 15&1/8" concert poster/photostat (image was used as a newsprint ad) for the Grateful Dead appearing at Madison Square Garden in New York City from 9/4-6/1979.
Photo by Herb Greene, show was promoted by John Scher Presents (this example comes from the promoter's archive).
Medium-thin glossy-coated index stock (Kodak photostat paper) poster is in very good to excellent (B/B+ to B+) condition; there is a tiny surface pull in the upper right corner, along with a few tiny stress creases/handling dings hiding within the image area, a thin horizontal crease going across Mickey Hart's face and a hint of surface wear, otherwise fine.
Likely unique/one-of-a-kind Grateful Dead concert artifact from a FANTASTIC set of late-'79 shows at MSG. Listen to a decent audience recording of the 9/4 show HERE:
