Interesting bio of the artist here and here. Berenice was a photographer, sculptor, and a poet in the 1920's, and became a darkroom assistant to Man Ray before starting her own studio in Europe.
During a visit to New York in 1929, she was inspired by the potential of a photographic project highlighting NYC architecture and design. This evolved into her CHANGING NEW YORK position via the Federal Art Project.
A fascinating project: FRAGMENTS by Kumi Yamashita.
“FRAGMENTS consists of resin tiles which cast the shadow profiles of 40 New Mexican residents of different backgrounds and ethnicities... It is both testament and celebration of the people whose names may never make it into the history books or history museums, but who definitely make up the rich fabric of life in a pueblo, city, county, and state."
A tighter shot of some of the faces shows the nuance involved.
