What a wonderful, brilliant, cool concept! Sketchtravel is a project that has taken one sketchbook around the world to 60 different famous illustrators, with the end foal of giving money to charity.
Each artists had one page to fill, and then they would pass it off to the next artist (all passes had to happen in person, no mailing, which is an interesting detail!).
And now that the book is filled, it is going to be auctioned off to raise money for the non-profit Room-to-Read, which focuses on child literacy.
Check out this trailer to see more. The animation is really clever!
Also, the website is awesome.
