Traité pratique des tirages photographiques
A practical photography manual by Charles Sollet and Emile Puyo, published in Paris by Gauthier-Villars in 1902 for photographers working on print processes. The only picture is a small printer's device: a heraldic shield with a crossed anchor and motto banners reading LABORE ET ... and CONSTANTI, set on a plain cream page, useful to a designer looking for vintage emblem and crest motifs.
