The image is a photograph of a sign on the wall of a subway train. The sign is rectangular in shape and has a white background with black text. The text reads "Surf the train, and you could get wiped out-forever. Ride inside. Get there alive." Below the text, there is an illustration of a person surfing on a wave. The illustration is in red and blue colors and is surrounded by a blue border. On the top right corner of the sign, there are two buttons - one for the MTA logo and the other for the train's logo.
