Set of (3) original 1st printing concert posters (one full-color 15&5/8 x 23&1/4" poster with a pair of 18 x 24&1/2" test proof sheets (full three-color test and black/white positive) for the Grateful Dead appearing at the Centrum in Worcester, MA from 4/7-9/1988.

 Art by George Sargent/Dragonfly Studios, medium-thin glossy stock posters are all in near mint to excellent (A-/B+ to B+) condition; they all have light handling/edge creases (the proofs both have a few minor roll bends going across the top margin) and there are a few other fairly minor issues (the odd stress bend/edge ding or two lurking within the image area), but the set as a whole is quite nice.

 Great-looking set of late-'80s regional Grateful Dead posters from New England featuring a very cool 1960's-inspired design. Check out audience-shot video of the 4/7 show HERE:
