For the last eight years the Sketchbook Project has amassed an astonishing collection of more than 30-thousand crowd-sourced sketchbooks from every corner of the world. This books features some of the best and most fascinating pieces in the collection. #colossal
Unique Idea I saw at http://americajanespeaks.net/2010/07/unique-value-project-idea/
Pick a theme and order a sketchbook (costs vary from 25-75) fill it with your art, doodles or whatever. Send it back and it becomes a part of a library of sketchbooks. It gets it's own barcode so you can see where it is and being looking at it.
