We've told you before about the Green Patriot Poster site, where users have been submitting posters raising awareness about climate change. Now, Ed Morris of the Canary Project (who is behind the GPP), has let us know that they're putting a book of posters from the site out, and he's looking for more submissions.So, if you're a designer (or an aspiring designer), you have until March 27 to upload your poster to the GPP site for it to be considered for inclusion in the book. The book itself will be out in the fall, and has designs contributed by luminaries including Shepard Fairey, DJ Spooky (Paul D. Miller), HunterGatherer, and many more. You should try to get yours in there, too.
