By themselves, Jimmy Page, Robert Plant, John Bonham and John Paul Jones may not have been household names, but collectively, they formed one of the most important rock and roll bands in history: Led Zeppelin. From the group's early days in 1969 comes this set of tri-colored tickets from a Bill Graham-promoted show in San Francisco that cost an amazing $3.50. Terrific period graphics highlight the set, which is in NRMT condition.
