Rare double-sided handbill for performances by The Doors and Jefferson Airplane at Middle Earth, New Roundhouse, Chalk Farm, London, on September 6 and 7, 1968, 6.75 x 10, featuring The Doors on one side and Jefferson Airplane on the other. In very good to fine condition, with light creasing and intersecting folds. Accompanied by a certificate of authenticity from Tracks. This was an unusual bill as The Doors opened for Jefferson Airplane on the 6th, reversing the order for the 7th so Jefferson Airplane opened. These were the first shows of The Doors' 1968 European tour and they went extremely well; Jim Morrison would later cite the show on September 7th as one of the band's best performances ever.
