Summer Holiday.

Probably the most photographed celebrity of the 20th Century, Marilyn Monroe was no stranger to the lens. What makes this image so special is that it is thought to be the last photo ever taken of her before her untimely death on August 5th, 1962. This photo, taken from the collection of pianist Buddy Greco, was shot only five days before her death.

The weekend they were taken is now legendary - it was during this trip that Monroe was allegedly urged to keep quiet about her affair with the Kennedy brothers.

Her death is still surrounded by conspiracy theories to this day, with many believing she was murdered to make sure she never revealed the liaison.

What's more intriguing is that they also feature Peter Lawford, who has been alleged to have been in a plot to let her die. According to an FBI report released in 2007, Lawford, a friend of Monroe and brother-in-law to Bobby Kennedy, helped trick the actress into committing suicide.

The report - which was not authenticated but was given to top FBI officers - claimed that this was aimed at preventing her revealing her affair with John F Kennedy and Bobby,

Monroe was said to have been told she would act out a stunt to spark kindly publicity but was left to die after she took an overdose.

The file claims Bobby Kennedy rang Lawford - who was married to his sister Patricia - to check the actress was dead so that his secret was safe.

Lawford and his wife had taken Monroe to the lodge in Nevada to see a Frank Sinatra show, who was also another lover Monroe was linked to.

She is said to have started bingeing on alcohol and pills once at the villa and was later taken home because she was allegedly in such a state.

Greco has claimed that the Monroe was in 'good spirits' towards the start of the weekend but later being 'out of sorts'.

Mafia boss Sam Giancana, her former husband and baseball player Joe DiMaggio, as well as Dean Martin, were all on the trip, as was Marilyn's hair stylist and famed celebrity hairdresser Jay Sebring.

Apart from Marilyn's overdose on an exorbidant amount of barbituates, the photos appear to be cursed - Sebring was later murdered by the Manson Family in 1969. Of the 36 photos taken, the other 30 photos were stored in an office in the World Trade Center and were lost when the towers fell on September 11 2001. The remaining photos have been sinced auctioned off.
