A set of 15 prints by Mexican photographer Manuel Alvarez Bravo is valued at £12,000-18,000 ($19,351-29,026) ahead of a sale at Phillips London on November 18.
The lot comprises some of his best known images, including Tentaciones en casa de Antonio (Temptations at Antonio's house) (1970).
Bravo (1902-2002) is the most significant Latin-American photographer of the 20th century.
At first, he drew his influence from the surrealists and cubists, but gradually began to explore explicitly Mexican themes (particularly death, folklore and religion) - reflecting the cultural awakening that followed the revolution.
Alfred Stieglitz' The Steerage (1907) is also likely to perform well.
The image is considered a turning point in the history of photography, as it represents one of the first documented applications of modernist principles to the medium.
Phillips comments: "The Steerage not only depicts human migration at a time of technological change, but as an icon of 20th century art it also encapsulates photography's coming of age as a fully modern art form."
It's expected to make £9,000-12,000 ($14,513-19,351).
A portrait of Stieglitz' wife, the painter Georgia O'Keefe, made $302,500 at Phillips last year. His auction record was set at $1.4m for another study of O'Keefe in 2006.
