take a look, it's in a BOOK

BOOK is a floating sketchbook project. Two artists in brooklyn, two in ireland mailed a book back and forth to eachother completing a new spread based off the previous. they did this once a week until the book was full. now it's on display.
This is by no means a new concept but the work produced is damn nice and definately worth a share. But... you don't have to take my word for it.
