Five portraits including two self-portraits, one of which shows Estanave sitting with a large wooden studio camera, sculpture studies, an image of a skull, a view of gravestones, a flower study inscribed and dated 1er cliché en relief - Paris 1909, three reproductions of posters, and two studies of geometric forms.

Estanave was a disciple of Gabriel Lippmann who is perhaps best known for having produced a process of direct-colour photography based on the inference of light by using a grainless albumen emulsion. In 1908 Lippmann also developed a photographic plate, on which a negative would be formed without the use of a photographic lens, and the positive of which would give a stereoscopic impression. Estanave experimented with both these process, producing plates such as those which are offered here.
