A beautiful first printing of FD-89 (OP-1), the Rick Griffin designed poster advertising Quicksilver Messenger Service, the Sons of Champlin and Taj Mahal at San Francisco’s Avalon Ballroom, in October 1967.  This is one of Griffin’s most sought-after designs, and this example, in near mint condition, is as nice as you’re likely to ever find.  Some faint handling, but overall bright, clear and unfaded.  14 15/64″ x 20″.
