Full, unused concert ticket for Led Zeppelin’s February 27, 1975, show at the Sam Houston Coliseum, 3.5 x 1.5, with a Lone Star beer advertisement on the reverse. Ticket is housed in a Lucite holder and is in fine condition. Playing 38 shows in 24 cities between January 18 and March 27, the tour had its ups and downs, as Jimmy Page was recovering from a broken finger and Robert Plant suffered with the flu, forcing cancellation of one show. Despite the problems, the tour was the band's most successful to date. RRAuction COA.
