I am convinced that Norman Rockwell (1894 - 1978) was and will remain one of history's coolest artists. Just check out his April Fools' Covers for The Saturday Evening Post. 'Nuff said, right? From the big picture to the smallest elements, he was certainly someone who paid attention to detail. See if you can spot all of the "errors" peppered throughout the awesome works of art, and then head over here to see what you've missed.
