These expressions of solidarity are reflected in the lithographs in which the figure of the proletariat is at the center of several caricatures : Ouch therefore proletarian ! by Benjamin Roubaud ( Le Charivari, December 1, 1833) and Do not rub it ! Daumier, published in Monthly Association (June 20, 1834), a supplement created by Philipon to train, by voluntary subscription, a reserve fund . In this lithograph, considered by Philipon as "one of the best political sketches made in France", a typographer full force at the forefront defies away frail figures of Louis-Philippe and Charles X. However, Philipon remain a Republican "patriot" in the tradition of 1789, more sensitive to political freedom only if the working masses.
