This composite image was created from pictures that I took of London (2005), New York (2010), and Tokyo (2017). These three cities are generally considered the world financial centers, each home to one of the major world stock exchanges - the London Stock Exchange, New York Stock Exchange, and Tokyo Stock Exchange. The colors represent the colors used to indicate stock prices at the end of the day - red for a loss, green for a gain, and blue for unchanged, with London being red, New York being blue, and Tokyo being green.
