Comic books and letters go together very well. Don't believe me? Well, I run a letter writing organization and work in a comic book shop so I may be slightly biased, but how about believing this project by Youseph Tanha. I posted before about his tutorial for turning comics into envelopes. Lately, he's been documenting the results of a curious mailing endeavor. Back at the beginning of September, he sent out 100 letters to people who had written in and given their mailing address at the back of Transformers comics. Unsurprisingly, he got back a pile of NIXIES, but he's also been getting actual responses and posting them on his blog. Pretty freaking cool!
P.S. Image is from Lumberjanes which is awesome. Everyone should read it!
