Original 1st printing 8&1/2 x 11" concert flyer for the Grateful Dead appearing with the Oxford Circle at the Avalon Ballroom in San Francisco, CA on 11/4-5/1966 (dates listed on flyer are 11/3-4). Art by Alton Kelley and Stanley Mouse, image is # 33 in the Family Dog/Avalon series. Thin flat stock flyer is in absolutely stunning mint to near mint (A/A- to A-) condition; only a whisper of handling and an almost invisible age spot in the bottom edge keep this one out of the "virgin" category, but it's pretty much as close as you can get. VERY clean example of this early Grateful Dead image from the Avalon.
