Threadless.com is the phenomenally successful T-shirt company with millions and millions of tees sold since it began in 2000. It pioneered the online business model of crowd-sourced or community-driven design, in which people submit designs that are voted on by the site's 1 million users and printed. Over the past 10 years, the company has amassed a vast archive of very cool, very hip, and often very entertaining designs, and Threadless is a spectacular showcase of 300 of the very best T-shirts created by the community--a barometer of art and design over the past decade. Much more than a book of extraordinary graphics, Threadless tells the extremely interesting story that inspired Inc. magazine to hail Threadless.com as ''the most innovative small company in America.'' There are also profiles of individual designers and ''think pieces'' from influential admirers, including design guru John Maeda, Jeff Howe of Wired, and bestselling business/marketing writer Seth Godin.
