Physiologie du théatre
Physiologie du théatre is an 1841 Paris satirical sketchbook by Louis Couailhac with illustrations by Henri Emy and J. Birouste, aimed at urban readers curious about theatre life and its audiences. The four pictures are pen-and-ink crowd scenes: top-hatted men gathered in a street, a trio seated at a café table, a crowded room of hatted figures, and a figure dropping onto a staircase, drawn in loose hatching with caricatured faces that a designer could borrow for lively period character studies.
