Wolfgang's Vault psychedelic rock posters
Wolfgang's Vault is a great site that allows you to stream classic rock concerts absolutely free. And they also sell a range of classic rock posters from the psychedelic age.
Typical are the two featured here for The Yardbirds at the Filmore Auditorium in San Francisco in 1967, with artwork by Bonnie MacLean and The Who at Filmore East in New York in 1968, designed by Helen Hersh.
Different version are available for each, from original first prints through to more modern re-prints. And as such, the prices vary considerably - from $48 (£24) for a recent print through to nearer $2.000 (£1,000) for an original.
