Frank, the poet with a camera, is known above all for The Americans, first published by Delpire in 1958, which changed street photography. He began, though, in the ferment of post-war Paris, and the stays he made there between 1949 and 1953 shaped the rest of his life. Mary's Book is the handmade book of that period, made for Mary Lockspeiser, and it comes out of the years before everything else.
