A set of 80 colour prints from George Barris' Last Photos series featuring Marilyn Monroe is valued at $60,000-80,000 at Heritage Auctions.

The sale will take place in New York on April 5.

Barris was one of the last people to photograph Marilyn Monroe

The photographs are signed by the artist and were taken in June and July of 1962, with the last captured just two weeks before her death in August.

They show the star on the beach at Santa Monica and at her home in the hills overlooking Los Angeles.

In September 2013, a complete set of Bert Stern's photographs of Marilyn Monroe titled the Last Sitting (taken in June 1962) made $41,000 at Freeman's.

We have this card autographed by Marilyn Monroe for sale.

An original print of Irving Penn's iconic portrait of Picasso is estimated at $50,000-70,000.

The photograph was taken in Cannes, France in 1957 and is one of only 30 signed copies.

Penn (1917-2009) is best known for his work in the field of fashion photography and in particular for his pioneering pieces for Vogue magazine. His minimal and elegant style went on to inform generations of photographers.  

In 2008, an aluminium-mounted platinum-palladium print of his Picasso portrait made $133,000 at Christie's New York.

A portfolio of 20 photographs by Brett Weston (1911-1993) is to auction with a $30,000-50,000 estimate.

All the images date from 1970-1977 and display the artist's unmatched eye for the abstract forms evident in everyday life.
