Opposite the fresco and the pissotière is the Musée Gabriel Chevallier, a small room with a wealth of (mainly pictorial) information on the writer, including some of his drawings.
A representation of Chevallier made at an unknown date.Chevallier is all over Vaux, and within a few seconds of the square we encounter representations of his characters. Bernard Pivot, the ex-chair of the Goncourt panel, was born here and has a school named after him, but Chevallier reigns supreme.
