An interesting twist on the old push-button interactive transit map. Instead of pressing a button to map out your route, here you press a button to find out where in Detroit’s downtown area to board your bus or streetcar. Although difficult to make out, the text along the bottom of the map seems to read: “To locate your loading zone, press button on your line.” I’m not entirely sure how successful this innovation was, as everyone in the photo seems to have an air of confusion about them.
