Flesh + Blood (1980) Models: Apparently, no one knows who they are. They were just models hired by the photographer, and the cover was designed by Peter Saville with no input from Ferry.
Stranded (1973) Model: Marilyn Cole. Ferry had noticed her when she was Playboy's Playmate of the Month for January 1972, and they dated briefly after the shoot. She is now a boxing writer. No, I am not making that up.
For Your Pleasure (1973) Model: Amanda Lear. She was briefly engaged to Ferry, according to Wikipedia, with the affair apparently starting after she had been asked to pose for the cover. This was all in between affairs with Brian Jones(she was the inspiration for "Miss Amanda Jones" on Between the Buttons) and David Bowie, and she also served as a longtime muse for Salvador Dali. Also, may have been born male, which if it's true, the surgeons did a good job.
Siren (1975) Model: Jerry Hall. During the cover shoot, Ferry gallantly held an umbrella over the 19-year-old's body to keep her blue body paint from melting off. She fell for it. Five months later, Ferry proposed to her. The following year, Mick Jagger invited the two of them out for dinner, and later chased her around a Ping Pong table trying to steal a kiss until Ferry ran him off. But in 1977, with Ferry away on tour, Jerry found herself at Studio 54, seated between Mick and Warren Beatty. Mick won, and Jerry dumped Ferry. He never spoke to her again.
