Original 1st printing 14 x 19&7/8" early 1967 fan club promotional poster for the good ol' Grateful Dead. Art by Stanley Mouse (whom also SIGNED the poster in pencil) and Alton Kelley featuring photos by Herb Greene, image ("The Golden Road to Unlimited Devotion") is featured in the Art of Rock book on page 187 (plate 2.192). Medium-thick flat vellum stock poster is in beautiful near mint (A-/B+) condition; only a tiny bit of age spotting near the bottom, a whisper of handling and a tiny black ink smudge in the left margin, otherwise it is a fantastic-looking example of this perennially popular Mouse & Kelley Grateful Dead image from the AOR. Here's a killer Winterland show (BG 55, if you're curious) from right around when this poster came out;
