Letters from Marilyn Monroe, Dwight D. Eisenhower and John Lennon are among hundreds of historical documents being offered in an online auction.

Monroe tells acting coach Lee Strasberg in a handwritten, undated letter that she can't concentrate on what she is trying to learn. That note, written on Hotel Bel-Air letterhead stationery, is expected to fetch up to $50,000.

A collection of 58 letters that Eisenhower wrote to his wife, Mamie, while he was the Allied commander during World War II could bring up to $120,000.

And John Lennon's letter to Paul and Linda McCartney around the time of the Beatles' formal 1971 breakup could bring up to $60,000.

They are among 250 items being auctioned May 30 by the documents dealer Profiles in History.
