Paperback covers out of time

First, this gloriously psychedelic Charles Moll cover from 1972.

Another cover from that decade, considerably less psychedelic, by Josh Kirby (presumably no relation to the time warrior).

Then an uncredited cover from 1958 showing the decade’s terror of Youth Running Wild.And finally a Mark Zuckerberg cover from 1964, the era when the Berlin Wall had made the city endlessly fascinating to spy novelists. If you’re curious about Chester Drum, here’s the lowdown.#SFWApro. All rights to images remain with current holders.
