The phototypogravure is a half-tone process on zinc and steel invented by the Maison Goupil which allowed simultaneous printing of photographs and text, thus enabling publication of photographically illustrated books and magazines. A course screen is visible on inspection suggesting this is a half-tone process.

The caption to this print reads… "We offer our readers today a specimen phototypogravure obtained by Mr. Sgap, after a photograph by Mr. Taupin."
