Original 1st printing 23 x 29" untrimmed printer's proof concert poster for the Grateful Dead's legendary acoustic/electric shows held at Radio City Music Hall in New York City from 10/22-31/1980.

 Art by Dennis Larkins (with Peter Barsotti),thick glossy-coated index stock proof sheet is in near mint to excellent (A-/B+ to B+) condition; really nothing more than a couple of ULTRA-tiny edge/corner-tip bumps and a few well-camouflaged handling dings hiding within the image area, otherwise it is an absolutely FANTASTIC example of this iconic Grateful Dead poster from NYC.

Check out remastered pro-shot video from the 10/30-31 shows (from "Dead Ahead") HERE:
