This is a superb addition to the recent Top 15 Zazzle Calendars for 2011 post. I wish I had seen it earlier but it's never too late for presenting great artwork. The Urania 2011 Calendar is full of Franco Brambilla's science fiction illustrations and, man, is he great!
Franco is an Italian illustrator and founder of Airstudio creativity lab, with a rampant imagination and incredible skill. Don't miss his store or you'll miss out on stuff as astonishing as this:
His Invading the Vintage series is based on the idea of aliens invading vintage postcards. And it's very, very good!
