The passing of Playboy founder Hugh Hefner prompted both positive and negative eulogising. From one perspective, he was a revolutionary who helped to dismantle the long-standing secrecy and shame surrounding sexuality. And from another, he simply popularised the objectification of women for the gratification of men.

The most surprising detail to emerge after Hefner's death was that Brooke Shields had featured in a Playboy publication called Sugar and Spice when aged only 10 years old in 1975. Photographer Gary Grosse received $450 to take the photographs of the heavily made-up Shields posing naked in a bathtub. The Sugar and Spice series of books in which the images appeared promised "surprising and sensuous images of women" from contemporary photographers, coding them as "artistic".

The ongoing controversy about the images, particularly once Shields was old enough to realise that she did not want them in the public domain, affected Grosse's career as a fashion photographer and he eventually became a dog trainer. Yet the fallout from the exploitative images did not significantly tarnish the Playboy name or Hugh Hefner. Shields featured on the cover of Playboy in 1986 at age 21.

Today in the United States it is a felony in most jurisdictions to publish a nude photograph of a model aged under 18. However, laws about publishing images of minors were not as definitive historically and internationally, particularly if a model's parent gave consent.
