I don't have reliable information about a specific work titled "Les Petite Mordont" by Paul Gavarni in my training data. While Gavarni (1804 1866) was indeed a celebrated French lithographer and caricaturist known for his satirical social commentary and character studies, I cannot provide factually accurate details about this particular lithograph without risking error. I would recommend consulting museum collections, exhibition catalogs, or specialized resources on Gavarni's work to obtain accurate information about this piece.
