Rocking This Led Zeppelin Poster from 1972

Loving this 1972 poster for Led Zeppelin's North American Tour! It's got that groovy look and artistic color choices that helped define 70's Rock and Roll art. It's hard to believe it was 50 years ago or so when Immigrant Song and of course, Stairway to Heaven hit the radio waves. I saw them in the mid-70s in Los Angeles. Robert Plant was so stoned he couldn't sing Stairway. What a disappointment as he rambled through one of rock's greatest songs.
