Poland's state treasury obtained the candid shots of Monroe -- taken by a friend, Milton Green -- in a collection of nearly 4,000 photographs it received as part of a 1995 foreign debt settlement.

Monroe is snapped dressed in jeans fixing her lipstick and hair, eating a meal and coyly chatting on the phone in several photos.

The "Some Like It Hot" actress died on August 5, 1962 from a barbiturate overdose at her Los Angeles home.

The Dom Aukcyjny Desa Unicum auction house is placing a total of 240 photographs on offer in the November bidding, which will have a fixed minimum of 72 euros ($93) per photo.
