This document appears to be about the French artist Jacques-Émile Blanche and his portraits of many famous writers, artists, and public figures from the late 19th and early 20th centuries. It includes reproductions of some of his portraits and discusses his use of mirrors in some works, including portraits of a model named Desiree Manfred where she is depicted near or interacting with mirrors. The document questions why Blanche did not receive more recognition during his lifetime.
