Rare large sized handbill, 16 x 5, advertising the Pop Proms held in June-July 1969. The first night was headlined by Led Zeppelin, with other performers during the seven-night engagement including Fleetwood Mac, Family, Incredible String Band, and Chuck Berry. The final night was headlined by The Who with support from Chuck Berry. Berry was uncomfortable with the playing order, as he topped the bill the night before, so he was allowed to close the first of the two shows. In fine condition, with a single horizontal fold and some small spots of tape toning to edges and corners. Accompanied by a certificate of authenticity from Tracks. Zeppelin was called back for three encores after their electrifying performance. RR Auction COA.
