Original 1st printing 8&1/2 x 11" boxing-style concert flyer, "Let's Go Tripping", a multi-act show featuring the Baytovens, the Hedds, the Intruders, the Illusions and the Friendly Stranger(s), held at California Hall in San Francisco, CA on Halloween night, 10/31/1966. *this was the show the Dead played after backing out of the Acid Test Graduation

 Designer unknown/not credited, image is featured in the Art of Rock book on page 174 (plate 2.142). 

 Thin flat stock letterpress flyer is in excellent (B+) condition; there are a pair of VERY light flattened horizontal/vertical bends, along with a couple of soft edge bends/light creases and a tiny edge nip or two scattered around the outer margin area, a whisper of handling wear and a stray pin-prick spot or two lurking within the image area, otherwise fine.

GREAT-looking example of one of the more elusive California Hall items from the AOR, this is only the second or third example I have seen.
