Stranger in a Strange Land won the 1962 Hugo Award for Best Novel and became the first science fiction novel to enter The New York Times Book Review’s best-seller list. In 2012, the Library of Congress named it one of 88 “Books that Shaped America”.

Shown here are two covers for Berkley’s paperback edition of “the best-selling underground novel by the dean of American science fiction writers.” The one depicted below came first, in 1968. In 1970, it was superseded by a new design, albeit with the same typography.

When used in caps, Karlgeorg Hoefer’s Permanent Headline (1964) can look a lot like Walter Haettenschweiler’s Schmalfette Grotesk (1954). It’s not quite as round, and the spine in S is less steep. Compare Schmalfette Grotesk to Permanent Headline.
