Picabia, Léger, Gris and Delaunay were regular members of the Sunday discussion group Villon — along with his brothers Duchamp and Duchamp-Villon — hosted at his home in Puteaux. Villon’s neighbour Kupka was a frequent visitor too, as were Apollinaire and Laurencin, Gleizes and Metzinger. Many of these remained long-term friends (although Kupka grew increasingly embittered). Villon met Toulouse-Lautrec in the late 1890’s, sharing a taste for Parisian night-life and a trade designing posters; the older Toulouse-Lautrec was an early formative influence.
