I have the first 25 or so issues of Spawn as well as a good few early The Maxx issues. I have first issues of pretty much all the Image series that came out right after Image was created.
Related to Spawn:
My collection also includes an autographed copy of Todd McFarland's first issue of The Amazing Spider-man #298 (if y'all haven't figured it out yet, Spidey was my favorite when Iwas a kid).
I have a pretty snazzy colection, actually. I'm the envy of all the dorks I meet.
