A beautiful Mint Condition concert poster advertising 1966 shows at San Francisco’s Avalon Ballroom featuring the Grateful Dead, Moby Grape and the Steve Miller Band (an incredible lineup!)  This psychedelic classic, printed only once, features artwork by the great Victor Moscoso.  It is FD-40 in the Family Dog concert poster series, and often referred to as “Hippy Santa Claus”, for obvious reasons, as well as pre-Christmas timing of the shows.  Moscoso has referred to it as “The Satanic Santa” because of Santa’s small horns.) A fresh and unfaded example you’ll never need to upgrade.  14 15/64″ x 19 61/64″.
