While browsing at my local Barnes and Noble for a gift during the holidays, by sheer luck I found a Presidential Doodles
book lying next to Miami: Then and Now
(one of my favorite photo books). Inside, there were doodles drawn by Ronald Reagan, FDR, JFK, George Washington, and other presidential heavy weights. You can clearly see a cultural difference between the drawings of George Washington (mathematical doodles) and say, Ronald Reagan (cowboy doodles). I'm hoping to pick this baby up in the coming weeks after the Christmas aftershock.
