For a cool memento from your travels or some modern wall art in your city apartment you should grab a poster from Line Posters. Line Posters are designed in Brooklyn, NY and feature city transit systems in simple - yet recognizable - graphic lines. The City Transit posters are visual representations of some of the world's most well known mass transit systems. The designs manage to tame the chaos and complexities of transit down to their form taking away the functional elements.
The current cities available include New York City, Barcelona, Madrid, Sydney, Chicago, Boston, Paris, Philadelphia, Moscow, San Francisco, Tokyo, Seoul, Berlin, London, Los Angeles and Washington D.C. The posters are priced at $20 for 12"x16" and $28 for 18"x24". T-shirts are also available for $28.
