The fact that it took so long for photography to get any respect is illustrated by how long it took for photographs to appear on book jackets, fiction in particular. When photos did appear they did so in France and on the noir tip, naturally. The Simenon is one of the first series of books he published under his real name, starting 1931. The Fantômas is from the 1932 second edition (after two decades of reprints). Both were published by Arthème Fayard, while the slim 60-odd-page Collection Police and Police et Mystère series (1932-1940) were put out by Ferenczi. The photographers repeat from one house to the next: Studio Piaz (best known for showbiz portraits, lasted into the 1950s), Lecram ("Marcel" backwards), Henri Manuel (a maker of official portraits, then an image factory), Hug Block (once Robert Capa's employer). Together they might make up the output of a small-time movie studio, with the Fayard titles upholding the high end like solid B pictures and the Ferenczis fizzing like slap-up improvised two-reelers.
From a folder I keep on my desktop called "random stuff" (don't we all have one of those?). I have no idea where most of these images came from so I can't link to (or vouch for) their sources.
