A collection of more than 100 previously unpublished photos of Marilyn Monroe can be seen for the first time in a new book. 'Marilyn: August 1953', published this week by Calla Editions, features digitally restored black and white images taken during the summer of 1953 of a then 27-year-old Monroe. The photos were shot by John Vachon, on assignment for LOOK magazine in Alberta, Canada, where Monroe was filming 'River of No Return' with Robert Mitchum.
