Oh, yes! The snail mailed slash-zines. Once I would love to get my hands on some of those. I've heard about them but have yet to see in real copies of one. I've seen scalations online but once I'd love to just sit down and actually hold one and read it.
Also, the Snarry manga from Japan, which I also viewed online, so I am not certain it is an actual publication of just something thrown together by fans, but I would love to have some of that as well.
