Best Paintings of all Time

I never cared much about Cubism. But when studying the dynamic Futurism that came differing from the quiet and static Cubism it made me appreciate what I believe was the shocking initial intention of the very same Cubism. Umberto Boccioni (1882-1916) is in my opinion the most gifted cubist/futurist painter ever. His paintings 'Elasticity' and 'Materia' are particularly my favorites.
