lol nemo…the second painting has famous palette knife marks of Van Gogh, where as painting # three is “Dance at Le Moulin de la Galette” by famous french artist Pierre-Auguste Renoir 
i can just identify those at the moment
Pablo Picasso was an avant-garde who introduced Cubism…where as except for the last one non of them has cubist approach.
so i dont know what kind of source you were looking for?
ps. nice thread deej as people gonna see how they get fooled by others.
