I'm also working on a Punisher run, just started this summer so i'm not far in by any means. I grew up collecting everything Punisher, by the time I left high school for the Marines my entire room in my parents house was wall to wall Punisher. Wish I would have taken pictures back then, it was a sight to behold.
I like to think that growing up reading the Punisher had something to do with me wanting to be a Marine .
Sadly I had to sell everything with all the moving around the Marines required. Now I'm working to get some of it back.
Earlier this week I had some luck and won #5, #14, #15 all @ 9.8 on mycomicshop.com. Hope they get here soon.
