A Halloween 1966 Grateful Dead concert poster from San Francisco, CA, for the “Dance of Death Costume Ball.” Joining the Dead on this occasion were Quicksilver Messenger Service and Mimi Farina (Joan Baez’s sister). A really cool one-off psychedelic concert poster designed by Paul Hawken, enthusiastically discussed by collector Pete Howard of PosterCentral.com (phone 805-540-0020, email pete@postercentral.com).
