Keep yourself from getting lost on the major subways of the world with the Mighty Wallets Map Wallet. Mighty Wallets has skinned three wallets with maps of the subway systems of New York City, Chicago and London.

These wallets are a must-have for residents of the Windy City and the Big Apple. I can't think of a more subtle way to show off civic pride than by using a wallet covered in your city's subway system.
