Reader Sun Scramble was checking out Google Earth the other day and - on a whim, we're sure - punched in 40°42'49.23"N, 73°59'51.44"W. Lo and behold, what did he see? A giant GTAIV ad.
See for yourself, it's right there, dominating the nearby streetscape in Manhattan's Chinatown. Not a bad way to get some free, dorky advertising if you happened to have your ads up at the time.
