Bibliography : Georges Boudaille. Courtin, Gravures. Galerie Berggruen Cie, Paris VII, 1960. Reproduced on page 129. Note: Pierre Courtin uses his own technique here. He uses plates composed of hollows and protrusions, and a paper that he soaks to make it lose its glue and thus become softer, more porous, so that the color soaks into the texture and gives this final rendering.
