Crestock.com has these great propaganda poster parodies. Some are hysterical. I've always been a fan of propaganda art style if not the content.
I really dig the work of Pascal Campion, too. His compositions are great and his use of color and mood are incredible. Insane ability to capture the feeling of place or action scene. Check out his great animations.
He has a grat blog he keeps with fellow francophile Mathieu Forichon. There are incredible pieces where the friends riff on a them back and forth.
