I saw the Walker Evans retrospective at the Pompidou Centre in Paris in June 2017. My daughter saw it with me.
From Wikipedia: 'Walker Evans (November 3, 1903 – April 10, 1975) was an American photographer and photojournalist best known for his work for the Farm Security Administration (FSA) documenting the effects of the Great Depression. Much of Evans's work from the FSA period uses the large-format, 8x10-inch camera. He said that his goal as a photographer was to make pictures that are "literate, authoritative, transcendent".'
