"The earliest drawing by Daumier that, so far, can be dated with precision is an unpublished study, not recorded by Maison, for the lithograph
The Napoleon of Peace (Le Napoléon de la paix) (LD 240), published in
Le Charivari of 3 May 1835, showing the composition in reverse."
Daumier, 1808-1879 published by the National Gallery of Canada, Ottawa with the Galeries nationales du Grand Palais, Paris and The Phillips Collection, Washington, D.C., 1999.
