A near mint first printing of BG-29, the 1966 poster advertising the Jefferson Airplane, The Butterfield Blues Band and Muddy Waters at the Fillmore Auditorium and Winterland in San Francisco. This classic by Wes Wilson is popularly known as "The Sound" and this is the beautiful color version. Other than some tiny chipping at the top edge (a millimeter of so from the top, in a few areas–very minor) and a faint, light handling crease in the top left corner this is superb. Measures 13 29/64" x 24 15/32". This poster is catalogued in the Eric King guide as BG-29-OP-2.
