Evergreen Review - Covers Archive
“The Evergreen Review was a literary journal published from 1957-1973. It’s pages were filled will content from contributing authors, poets, philosophers, and political figures that included Jean-Paul Sartre, Samuel Beckett, Albert Camus, Malcolm X, Hubert Selby Jr., William Burroughs, Supreme Court Justice William O. Douglas, Frank O’Hara, Timothy Leary, Norman Mailer and Charles Bukowski. The magazine was ressurected in 1998 in an online-only format and can be found here.”
Reality Studio (cool resource, check them out if you’re not familiar) has an online archive of the magazine’s first 99 covers, split into two sections: HERE and HERE. the first section is a bit more interesting to me (the 60s covers sort of descend into goofy naked hippie territory), but even those later issues always seem to contain some unpublished work by somebody like Samuel Beckett or Allen Ginsberg.
