The sketchbook project is a collaborative series of art books created by 5,000 artists around the world. Anyone, from anywhere in the world could participate in the project. You just had to sign up to receive a blank sketchbook in the mail, then fill it up and send it back. Your work would be cataloged in the Brooklyn Art Library and published in the Limited Edition art book series. One of them was my sis Nadia! Take a look of her great sketchbook!
