If you have ever visited London, in the fabulous red phone booths you will find "tart cards" for life's pleasures. These tart cards that advertises sexual services fill the phone booths sometimes where it is hard to find the phone. In a project to designers, they where asked to design their favorite type into a "type tart card". The project is on display in London now and here is a link to what they came up with from Wallpaper magazine. You will find the tart cards full of double entendres and ambiguity. Type can be a turn on for us design geeks.
