What was the first comic book you ever purchased?
For me it was Marvel Special Edition featuring Star Wars #1, a tabloid-sized collection of the first three issues of Marvel's Star Wars adaptation--the first half of the movie. I only had this first half, so I read and re-read the first half of Star Wars over and over. This of course was way back in the day before home video, so comic book adaptaions were one of the very few ways to relive a movie experience.
How about you--what was the first comic you bought?
