Danish designer Sebastian Campion put 300 t-shirts for sale at the Museum of Contemporary Art in Roskilde, Denmark. Each shirt in the Social Souvenir project has a different snip of text from an artist whose work is featured in the museum. When you buy one of the shirts, you provide your name and address to place you (and the shirt) on a Google Map. Above are my three favorites, with text by Brion Gysin, Laurie Anderson, and Yoko Ono.
