A collection of autographed Polaroid photos featuring stars like Robert De Niro, Sean Connery and Meryl Streep are expected to fetch up to $30,000 (£20,000) at auction next month (Nov13).

Photographer Tim Boxer swapped his Nikon F professional camera for a cheap Polaroid to snap his celebrity subjects after finishing professional shoots with them during the 1970s and 1980s and he persuaded the famous faces to sign the candid, instantly-developed pictures there and then.

He amassed a total of 212 rare snaps over the years, including shots of U.S. President John F. Kennedy's widow, Jacqueline Onassis, pioneering artist Andy Warhol, and a 12-year-old Brooke Shields after she shot to fame in controversial movie Pretty Baby in 1978.

The photos are now set to go under the hammer at Doyle New York on 25 November (13), reports the New York Post.
