On a label on verso: The Vanishing Race. This is perhaps the most popular and best known of all the Curtis Indian pictures, being internationally famous. It is a picture which the artist carried in his mind for several years and in which he endeavored to express the thought that the day of the Indian is drawing to a close and that they are literally riding toward the shadows of the last setting sun. The unusual beauty and quiet tragedy form the combination which has caused critics to pronounce this the most remarkable photograph ever.
