Lennon, Monroe letters go under hammer

Letters from John Lennon, Marilyn Monroe and Dwight Eisenhower are among hundreds of historical documents being offered in an online auction.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 cannot 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 dollars.
