This isn't car related but way back when I used to work on cessna airplanes, I built an elevator (Pitch flight control surface) for one of the planes from sheet metal. It is completely enclosed. The line crew guys and myself all signed our names and printed things like the current price of bread, milk, gas, etc. Kind of a time capsule of sorts. I wish that I would have taken a picture but back in those days you still had to take 35mm film to the store to get prints. We not only did not have cell phone cameras, nobody had cell phones. lol
