Proof of Marilyn Monroe’s cosmetic surgery procedures and details of a 1957 ectopic pregnancy are to go under the hammer as part of a macabre auction lot in California.
The star’s X-rays, medical records and doctors’ notes are to be sold at Julien’s Auctions Icons and Idols in Los Angeles on November 9-10.
Highlights of the odd lot include Monroe’s skull X-ray and notes from the office of Dr Michael Gurdin dating from 1958.
The lot is expected to fetch between $US15,000 and $US30,000 ($A16,000-$A32,000).
The patient was listed as Marilyn Miller, to protect her identity, and the doctor noted that her chief complaint was "chin deformity".
The records offer a fascinating medical history that starts in 1950 and ends in 1962, months before the star’s death.
Listed are a 1956 bout of Neutropenia in England; an ectopic pregnancy in New York and a 1950 cartilage implant in the chin that the doctor observed had slowly started to dissolve.
"Those with knowledge of the implant procedure have explained that this was done in association with a tip rhinoplasty, a procedure involving the tip of Marilyn Monroe’s nose only," says a spokesman for the auction house.
The last entry of the medical files, dated June 7, 1962, reports a fall between 2am and 3am resulting in swelling and tenderness of the nose.
Monroe was brought to Dr Gurdin by her psychoanalyst, Dr Ralph Greenson. Her alias at the time was Miss Joan Newman.
Included in the file are "six X-rays including frontal facial bones X-rays, a smaller X-ray that is a composite of the right and left sides of her nasal bones and four small dental X-rays into the roof of Monroe’s mouth, looking upwards toward her nasal bones".
Monroe was found dead in her Los Angeles home on August 5, 1962.
The Julien’s Auctions Icons and Idols event will also feature William Shatner’s signed shirt and boots from the Star Trek series, a mask worn by Clayton Moore as The Lone Ranger, a Katherine Walker-designed dress owned by the late Diana, Princess of Wales, a tracksuit James Gandolfini wore on The Sopranos, and the wedding gown Julie Andrews wore in The Sound Of Music, which is valued to sell for $US30,000-$US50,000.
