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.
