Sony uses street art to promote PSP

Sony has launched a new guerrilla marketing campaign that involves chalk drawings and fly-posters on buildings in major U.S. cities.

"The drawings, which depict children playing with giant PSP handhelds in various ways, were first sighted on the streets of Philadelphia. Since then, further adverts on the streets of New York, and reports of sightings in San Francisco and Chicago have apparently confirmed a concerted multi-city campaign for the images, likely beyond the abilities of a single PSP-loving independent artist."
