Marilyn Monroe's lost love letters to go under the hammer in December

Marilyn Monroe's lost love letters are set to go under the hammer next month at Julien's Auctions in Beverly Hills.

The 'Marilyn Monroe's Lost Archives, which consists Joe DiMaggio heartbreaking letters to the blonde beauty over her the breakup of their marriage, also include love letters from Monroe's third and final husband, playwright Arthur Miller, People Magazine reported.

One of the letters from DiMaggio said that he loves her and wants to be with her and there is nothing he would have liked better than to restore her faith in him, written when she announced she was filing for divorce after a matter of months in 1954 also features in the collection. The 300 items also includes a handwritten letter from Monroe to Miller in which the woman who was arguably Hollywood's greatest sex symbol muses about her many insecurities, while other letters in the collection come from such friends as Clark Gable, Cary Grant and Jane Russell, the latter imploring Monroe in 10 neatly handwritten pages to give her marriage to DiMaggio another chance.

Auction owner Darren Julien estimates the pieces could fetch $1 million  or more, noting a watercolor Monroe painted and planned to give to President John F. Kennedy went for $80,000  at an estate auction nine years ago.
