An amazingly chock-full sketchbook, the collective work of 4 artists. Just beautiful!

 
The backstory:

“In 2004, NY artist Oliver Jeffers, would exchange a sketchbook with 3 other artists and follow one another’s lead with a weekly illustration. Over the course of 36 weeks, each would respond to the previous artwork which proceeded them and then forward it onto the next in line. Once completed, the sketchbook had travelled over 60,000 miles, and crossed the Atlantic on numerous occasions.”
