A wonderful psychedelic timepiece from the Summer of Love featuring the Jefferson Airplane and the Grateful Dead for a full week’s worth of shows in Toronto, Ontario, Canada in the summer of 1967. Known as BG-74 to poster collectors, this Bill Graham concert poster is in shorter supply than most because most of them were allegedly confiscated by Canadian customs officials, or so legend has it. Enthusiastically discussed by collector Pete Howard of PosterCentral.com (phone 805-540-0020, email pete@postercentral.com). If this kind of window card floats your boat, be sure to check out more vintage psychedelic concert posters shown on this page found right here on my web site: http://www.postercentral.com/psychedelic.htm
