From his humble beginnings as an unknown street artist in Paris, JR has catapulted into mass media, thanks to his bold artworks and friendly personality. As many of his works are spread out around the world, it is hard to see the volume of his works at a glance. JR has developed a free App and Digital Art Book for the Apple iPad. The app can be downloaded from iTunes, and within it is a neatly organized catalog of his works. Furthermore, there is the digital version of his first publication, The Wrinkles of the City: Los Angeles, included inside for your viewing pleasure.
