Somehow, it’s been ten years already since Threadless emerged onto the scene. We’re not sure how this happened, as a few weeks ago it seemed Facebook was still reserved for .edu addresses and Altavista was still… well, around. But Threadless, the well-known online t-shirt store that prints the most popular designs from user submissions, has turned a decade old. In celebration, they’re putting out a book with some of the best, most creative, and most popular designs to pass through their hands from the online community. Featuring 400 designs crowd-sourced by the company that invented crowd-sourcing, the book shows how the graphic tee has evolved over the last ten years.
