For thirty -six weeks, this sketchbook traveled between four artists, two of whom lived in Brooklyn (Mac Premo, Duke Riley), and two in Belfast (Oliver Jeffers, Rory Jeffers). Each environment, the book fell to one of the participants. On Monday, he had to send her further. Each artist had 5 days to fill it. A small passage of each drawing was stretched to the next page. In addition, the participants did not communicate, except through the book.
