Katia Wish is awesome. She just sent me a link to a very complete gallery of Ilya Repin's work. Especially cool to check out all the studies he did for his major pieces. The man was thorough.
Anyways enjoy!!! Follow the link here!!!!
ps. This is the art nerd in me talking....but Rockwell and Repin were working at the same time roughly (1920s)...I wonder if they knew of each other. Can you image a collab piece between those two masters? An "Ilya Rockwell" or a "Norman Repin" if you will. But what if they really did create that painting but it's been lost!? But I digress.....haha
pps. Also check out the Zorn and Serov sections from the same site!: http://gallerix.ru/
