English: Street map of Philadelphia and surrounding area copied from the yhjjOpenstreetmap.org website by changing to fullscreen mode (F11), zooming until the city just filled the screen, then pressing the "print screen" key to save a 1920x1080 image. Top banner was cropped off. Cropped left and right sides to approximately a 1.276 aspect ratio, to focus on the city and to increase thumbnail image sizes. Slightly increased contrast and reduced brightness. Added a black line along the city boundaries. Added "Philadelphia Int'l" text by the airport. Removed some partial highway markers near left and right edges which were distracting and unnecessary.
