RARE GRATEFUL DEAD 1966 Fillmore Auditorium BILL GRAHAM Concert Poster BG-26. This Jefferson Airplane & Grateful Dead issue is a favorite among collectors and can be extremely difficult to find. The BG-26 is a creative leap forward for the work of Wes Wilson. This image represents the first time that the artist would incorporate a nude figure into his Fillmore poster art. This would be a reoccurring theme in Wilson’s work for the remainder of the time he was enlisted by Bill Graham. Performers include: Jefferson Airplane, Grateful Dead, P. Factor Jug Band, Andrew Staples, Quicksilver Messenger Service, Country Joe and the Fish. This would make an incredible piece for your collection or a very special gift for an adoring fan.
