We've seen these before, but there are a ton new portraits.
Artist, Steve Payne's statement from his blog replaceface.tumblr.com:
"George Dawe was an English portrait artist who painted 329 portraits of Russian generals active during Napoleon's invasion of Russia for the Military Gallery of the Winter Palace, Saint Petersburg, Russia. I'm using digital copies of these paintings as a basis for my own work which involves incorporating celebrities into the paintings using photoshop."
