"The Nib is wrapping up ten years of publishing and closing down at the end of August. But before we go, we are making all 15 issues of our Eisner and Ignatz award-winning magazine available for anyone to download for free. That’s more than 1,600 pages of comics, including our out of print Secrets, Nature, Food, and Color issues."
