A selection of candid snaps of Marilyn Monroe are expected to fetch $9,000 when they are auctioned this week.
The photos were taken by her friend, Hungarian-born photographer Andre de Dienes, on three separate occasions between 1945 and 1953.
The images show the actress frolicking on the beach, playing in the snow and posing at the Bel Air Hotel.
They are currently owned by a private collector who is putting the set up for auction at Nate D Sanders auction house in Los Angeles.

In the earliest photos, Monroe was just 19-years-old and still known by her birth name, Norma Jeane.
At the time, she was a model who had left her first husband James Dougherty and was hoping to transition into acting.
Dienes paid Monroe the hefty sum of $200 (the equivalent of £5,700 today) to go on a road trip with him where he would photograph her in natural landscapes.
One photo shows Monroe looking angelic as she sits in the snow on Mt Hood, Oregon, with another focusing on her face.
Dienes, who was a friend of Marilyn, said she thought she was an angel when they first met (Monroe pictured in 1949 on Tobey Beach, Long Island)

Describing their first meeting in his memoirs, Dienes said: ‘It was as if a miracle had happened to me. Norma Jeane seemed to be like an angel.
‘I could hardly believe it for a few moments. An earthly, sexy-looking angel! Sent expressly for me.’
Four years later, de Dienes took five photos of the starlet in swimwear posing seductively on Tobey Beach, Long Island.
The final two images were taken at the Bel Air Hotel in Los Angeles in 1953.

She seems in a very relaxed mood as she does a stretch in one photo, and reads a book in the other.
It was a big year for her with the release of the films ‘Gentlemen Prefer Blondes’ and ‘How To Marry a Millionaire’ which propelled her into super-stardom.
The photos are being sold by a collector with US-based auctioneer Nate D Sanders.
A Nate D Sanders spokesperson said: ‘It is rare to have such a large quantity of original Marilyn photos.
‘Andre de Dienes photos of her are some of the most collectible – the ones from 1945 are when Marilyn and him were in a relationship together and they remained good friends until her death.’
Monroe died of a drugs overdose aged 36 in 1962, and Dienes died in 1985.
De Nienes described Monroe as ‘a sexy-looking angel.’ The pictures used to belong to a private collector, who recently decided to put them up for auction. Pictured: Monroe on Tobey Beach in 1949
