I was in Rotterdam, but the exhibition there was horrible. Le Fauconnier has nothing to tell anymore. He has a dirty color now and has become a real academic. Mondrian is completely frozen, no poetry at all anymore. It's terrible that these people can not reach further with great ideals. To my taste Alma paints far too much naturalistic. A big difference, these three, compared to [Franz] Marc, Kandinsky, Filla etc..
