I love Blu--artist behind the famous MUTO animation. The image below are his drawings that were included in 25 Disegni, a publication of artists drawings. Each soft-cover, 48-page flip book features two artists, one going in either direction. Alas, the one seen here, featuring the work of Blu and Eric Ailcane, is sold out...but there are other interesting books to buy here.
Eric Ailcane (great website--check out his exhibition installations)
