John Blake is publishing a "nostalgia memoir", The Girl in the Spotty Dress, by Pat Stewart with Veronica Clark.
The book tells the story of Stewart who, after posing on the railings of the Blackpool promenade in 1951, found that the resulting photograph became an iconic image of the 20th century.
For years, an imposter claimed to be "the famous girl with the enchanting smile". However, after seeing her lying on "The One Show" about her involvement, Stewart decided to step forward to reveal herself.
Stewart's story - the "true story of the girl in the spotty dress" - evokes memories of the 1950s and 60s, as Stewart shares her experiences from half a century in the "golden age" of show business along the way.
James Hodgkinson at John Blake did the deal for world rights through literary agency Eve White.
John Blake will publish The Girl in the Spotty Dress: Memories from the 1950s and the photo that changed my life forever on 7th April, priced £7.99,
