Mame's bookbindery was probably the largest depicted in the 19th century. In this image there may be several hundred people working in the huge facility. No women are visible. Strangely, there appears to be a water fountain in the middle of the room. Dodd's Curiosities of Industry, Printing: Its Modern Varieties (1852) p. 10 suggests, probably with some exaggeration, that Mame may have employed as many as 1000 people in this department.
