Original 1st printing 8&1/2 x 10&5/8" concert flyer for the Calliope Company's "Dance of Death Costume Ball", which featured the Grateful Dead appearing with Quicksilver Messenger Service and Mimi Farina 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

 Artist unknown, image is featured in the Art of Rock book on page 174 (plate 2.143). 

 Thin flat stock flyer is in near mint (A- to A-/B+) condition; really nothing more than a couple of minuscule diagonal bends in the lower left/right corner tips and a tiny ding next to the first "D" of "Dead" (hard to see unless you tilt the piece towards a light source), otherwise it is a SPECTACULAR example of this semi-uncommon early Grateful Dead piece from a legendary Halloween show in San Francisco.

 No tapes exist, but he event was detailed on page 99 of Charles Perry's "Haight-Ashbury- A History": 

"At California Hall there was the Calliope dance with the Dead, Quicksilver, Mimi Farina and "six authentic witches". It was agreeably spooky. The balconies of the hall were hung with nets holding plastic baby dolls. A Headless Horseman with a flashlight shining out of his decapitated neck stalked the hall. At midnight a Giant Pumpkin wheeled Death, wearing a red brocade Louis XIV jacket, around the hall in a wheelchair while Quicksilver played "Bo Diddley".
