In the spring of 1984, a strange new comic book sat beside cash registers in select shops, too big to fit in the racks, and too weird to ignore.

Until it sold out. Again and again and again. For thirty years. Now, peek under the shell and see how this so-called “happy accident” defied every naysayer to become one of the most popular and beloved franchises in the world.
