Marvel Milestone Edition: The X-Men #1. This is the book that started it all. This is a reprint edition that reproduces the exact comic, ads and all, so it is really cool. It's like having my hands on the original without throwing away $3,000. Amazingly, the whole anti-mutant sentiment is here, loud and clear, a big wake up call in 1963. Magneto is really cool in here too. The great part is that Magneto is morally justified where it is very easy to see his side of things. In today's world, I think it would be really cool to have Magneto's plans be the center of a comic series.
