GPG is the publishing company responsible for the enormously successful 1994 release, "The Playboy Book: Forty Years -- The Complete Pictorial History," which has sold 200,000 copies in markets around the world.
"We are mounting the greatest Playmate hunt ever, seeking information and the means to contact those Playmates with whom we have lost touch over the years," said Gretchen Edgren, former Playboy magazine editor and author of "The Playmate Book."
Since Playboy was first published in 1953, more than 500 glamorous young women have graced the magazine's centerfold. "The Playmate Book" will include all of these Playmates plus those through June 1996.
"Our goal," Edgren said, "is not only to publish photographs and information on these Playmates as their millions of fans remember them, but to update the entries with new information about their lives and careers.
"With that in mind, we are asking those 'lost' Playmates and anyone who might have some information on them or their whereabouts to contact us as soon as possible."
A special "Playmate Book" hotline has been established to handle calls with information about Playmates who have changed their names, moved or otherwise "disappeared." Information may be made available to Edgren at 312-944-8701 twenty-four-hours a day.
"We are very excited about 'The Playmate Book,'" she added, "and we would be very grateful to any friends and fans who can help us contact the missing Playmates so that we can reunite them with the rest of the Playboy family for this project."
