Original 1st/only printing 8&1/2 x 11" benefit* concert flyer for Joan Baez (with Mimi Farina)** with the Grateful Dead and Quicksilver Messenger Service at the Mount Tamalpais Outdoor Amphitheater in Marin, CA on 10/8/1966. Art by Stanley Mouse and Alton Kelley, image ("PEACE") is featured in the Art of Rock book on page 228 (plate 2.325)- this is the 1st-state version (Joan Baez and Mimi Farina canceled and were replaced by Bola Sete). Thin flat stock flyer is in fantastic near mint to excellent (A-/B+ to B+) condition; a few scattered handling dings, an ultra-soft diagonal bend in the upper left margin and a stray tiny smudge or two, otherwise it's a great-looking example of this classic '66 Mouse & Kelley Grateful Dead image.

*show was a benefit for 1st Congressional District write-in candidate Phil Drath.

**Canceled, replaced by Bola Sete.
