Original 1st printing 16&5/8 x 24" concert poster for the Grateful Dead appearing at Madison Square Garden in New York City, NY from  9/14-23/1988.

 Art by Jackson, medium-thin glossy stock poster is in good to very good (B to B/B+) condition; there is a light to moderate degree of moisture rippling throughout the poster with the most concentrated/pronounced area extending from the lower portion of the image area down to the bottom margin, along with a few stray tiny edge dings/creases and a tiny edge tear or two scattered around the outer margin area, a few light handling/stress creases hiding within the image area and a bit of light age spotting on the reverse side, otherwise fine.

 Neat-looking late-'80s Grateful Dead poster from an extended set of shows attended by none other than King Kong himself. Check out the 9/23 show HERE:
