Holy cow, this is the coolest thing I've heard about in a long time. I never heard about Latin American cartonera publishers until Lars Palm just told me about them (I am just finishing his Teeny Tiny chapbook). This page is a great resource, and the flickr slideshow at the bottom of the page is awesome. These publishers use recycled cardboard to make unique book covers with painted (etc) designs, all in an effort to make literature more accessible. I love it.
