Original 1st printing 11 x 14&7/8" "phone pole" concert poster for the Grateful Dead appearing at the Downs at Santa Fe in Santa Fe, NM from 9/10-11/1983. 

Art by Dennis Larkins, medium-thin flat vellum stock poster is in good/decent (B to B/B-) condition; this example has been HAND-COLORED (in assorted colored markers) by an unknown party, along with a pair of tack holes in the top center and lower left margins, a few soft surface stains and thin bends here and there, a bit of relatively minor edge wear (tiny creases/nip tears), a hint of mild paper toning and a few soft stains/scuffs on the reverse, otherwise OK... most of the conditional issues aren't all that intrusive.

 Check out a GREAT audience recording of the 9/10 show HERE:
