Couleru. Nouveau Cours Élémentaire de Coloris et d’Aquarelle: Suivi de Considérations sur la Peinture Orientale. Paris (Monrocq Freres) n.d. (circa 1860). 
These charming images come from Nouveau Cours Élémentaire de Coloris et d’Aquarelle, an illustrated course of instruction in watercolor and crayon techniques for children and young adults. After an eight-page introduction offering 12 practical lessons for the budding artist, the pages that follow provide 11 examples of properly tinted drawings, each paired across a two-page spread with the identical illustration in black and white (for the student herself to color.)
The particular copy in our inventory at the moment has seen some use, which in my opinion, makes it all the more interesting.
I’ll reserve judgment as to our student’s mastery of the Nouveau Cours Élémentaire. Perhaps she might have paid a bit more attention to the book’s hand-tinted color guide?
Copy books such as this one were popular in their day. The verso of the title page advertises additional books in the Bibliothèque de l’École de Dessin Le Maitre de Dessin, which in its totality provides “6,000 feuilles d’études en tout genre, depuis 20 centimes jusqu’a 3 francs et au-dessus.” Very few, however, seem to have survived to the present day, as WorldCat only locates three copies of Nouveau Cours Élémentaire de Coloris et d’Aquarelle in North American libraries.
