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.

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

 Thin flat stock flyer is in good (B) condition; there is a moderate degree of creasing along the top margin and along the lower left margin, along with a tiny nip tear in the upper right margin/edge, a thin vertical roll crease along the lower left margin, a few light handling dings here and there, a 4-5" thin diagonal bend in the upper left margin/corner and a few tiny pin-prick age spots on the reverse, otherwise fine.

 Uncommon early Grateful Dead piece from a legendary '66 Halloween show in San Francisco. The 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".
