According to a report on popular street art/graffiti site Wooster Collective, Sony appears to be using distinctly alternative marketing methods to promote its PSP handheld in the run-up to the holiday season in North America, using chalk drawings and fly-posters for guerrilla marketing purposes.
The drawings, which depict children playing with giant PSP handhelds in various ways, were first sighted
by the website 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.
Wooster Collective originally considered the first set of drawings it posted to be the original work of a street artist, and commented of the second sighting: "Obviously they are the same thing as the alley graf in Philly. Obviously not done by a street artist. Obviously done by Sony and their ad agency", though noting of the campaign: "Our take - we like it." Sony has not officially announced this promotion, however, making it possible, though unlikely, that a group of independent citizens have stepped up to promote the PSP in paint and poster form.
