Centerfold

[4] Early on, Hefner required Playboy centerfolds to be portrayed precisely, telling photographers in a 1956 memo that the "model must be in a natural setting engaged in some activity 'like reading, writing, mixing a drink'...[and]... should have a 'healthy, intelligent, American look—a young lady that looks like she might be a very efficient secretary or an undergrad at Vassar.

'"[5] Hefner later said that the ideal centerfold is one in which "a situation is suggested, the presence of someone not in the picture"; the goal was to transform "a straight pinup into an intimate interlude, something personal and special.

"[6] Though the term has become linked in the public consciousness with erotic material or models, many other magazines such as Life, Time and National Geographic have published fold-out spreads on other subjects.

When obtained from one of the more prestigious publications in the field, it can become a semi-formal personal title used in news articles and introductions long after the model's centerfold appearance.

[7][8] Some online-only media outlets maintain a monthly designation reminiscent of a print magazine centerfold; for example, the Twistys Treat.
