From Wikipedia
Le bonheur de vivre is a painting by Henri Matisse. Along with Picasso's Les Demoiselles d'Avignon, Le bonheur de vivre is regarded as one of the pillars of early modernism. The monumental canvas was first exhibited at the Salon des Indépendants of 1906, where its cadmium colors and spatial distortions caused a public expression of protest and outrage.
