Nice!
Considering that a full long box holds approximately 250 bagged and boarded comics and multiply that by 50... your collection is at least double that of mine.
I was big into the early Image comics.
I loved the work of "hot" artists in the 90's such as Todd McFarlane, Jim Lee, Marc Silvestri. Those are the top three hottest artists of the 90's. An argument can be made for Rob Liefeld as well... but his style is either something you love or hate.
