Looking for a gift for the train buff in your life? Look no further. Underground Signs is a company that makes customized NYC subway signs. Not only can they recreate actual signs from the MTA’s 468 stations, they can also make completely personalized ones, like the Konami code above (video game nerds will get this one). The signs are officially licensed by the MTA. They also just obtained the rights to recreate signs from Boston’s MBTA. Traitors. Check them out at underground-signs.com!
