The picture shows a fresh-faced 15-year-old Monroe, then known as Norma Jeane Baker, standing with her whole class at Ralph Waldo Emerson Junior High School in Los Angeles.
The photograph, which measures 8x24 inches, is expected to sell for up to 1,500 pounds when it goes under the hammer at the auction in Stockport, Cheshire, next week, reported Mirror online.
Also up for sale at the same auction are nine Christmas cards sent by Charles and Diana, the Prince and Princess of Wales.
The cards, sent over successive years, feature photos of young William and Harry growing up and are signed by the royal couple with festive greetings.
