Pierre Apraxine: "Personal working album, annotated by the photographer about the quality of the prints or the difficulties presented by the subject matter. Invaluable document by one of the most gifted early amateurs, a pioneer in the rendering of movement in photography. These are the images which secure the photographer his place in history. This group of prints does not constitute a coherent ensemble, but rather a sampling of the photographer's work. We do not know if the projected album described in pencil draft on the title page was ever produced. With very few exceptions, the photographs assembled here are unique."
