Thank you very much, iside!
Concerning the "realistic" period, I would not compare it with Hopper, and with Wyeth. Hopper (who was very fond of) land, and your sugi brings with Wyeth (which is also very fond of) a certain "flyuidnost. Yes, and the mood they are, it seems to me closer.
A Dix and Gros - also, in my opinion, wrong. We sugi no inherent aggressiveness and some vulgarity.
And on the distant influence of Munch's nobody wrote? For me it is obvious.
I did not know that the artist must have thought to see a lot of times, but I like him. Very Italian - reminiscences mass
