Here's an example:
Card #511 -- Sam McDowell, San Francisco Giants
This card of "Sudden Sam" McDowell is really busy. Looking past the fact that a visual trick makes it look like he's throwing the baseball wildly, you see the batter, catcher, umpire and an infielder. Add to that the fact that the image is slightly tilted...it looks like Sam is about to tip over and the field appears crooked. Considering the era, it makes you wonder whether the photographer may have been in a certain frame of mind...
Sam McDowell was winding down his career as this card was printed. He would be pitching for the Yankees in June of '73, appeared on one more Topps card in pinstripes before pitching his final game.
