Janis Joplin, Payphone, San Francisco, 1967

Janis Joplin talks on a pay phone in this black-and-white shot taken in San Francisco in 1967. 

Her performance at Monterey Pop with Big Brother and The Holding Company made her an international star virtually overnight. (The D.A. Pennebaker documentary Monterey Pop captured Cass Elliot in the crowd silently mouthing, "Wow, that's really heavy," during Joplin's performance.)
