Today we have a puzzle. The postcard above comes with no information other than the caption on the front. Perhaps a solar eclipse was imminent or a display of alligator wrestling. They could be looking forward to a demonstration of tree-cycling or an enthralling trouser-pressing contest. The second image in this series comes from Catalina Island. The mystery here is not so much what they’re looking at (it’s a glass bottomed boat) but why is everyone wearing a hat?
