Due to the perspective in this drawing, each of these trumpet players is exactly the same size. Pay close attention to how the lines converge at the right side of this optical illusion picture. Now, next time you are scribbling on a sketch pad, see if you can mimic this eye trick! But please do it better than these weird looking toy soldiers that look like they were drawn in 1907 in Britain. Still, it’s a pretty strong, simple illusion that is easy to communicate.
