Mark Tryon was a pseudonym for one or more authors writing sexy pulp novels for a number of publishers in the 1950s and early 1960s. His name is particularly notorious, however, because his novel Sweeter Than Life aka Twisted Loves of Nym O’Sullivan aka Twisted Love was banned for being indecent. Sales of the book led to the arrest of a California bookseller and the landmark 1959 Supreme Court case Smith v. California. Ultimately, sales of the book were allowed under the 1st Amendment as protected speech. This is an AI-generated photo.
