For me too Zeck is by far the definitive Punisher artist. I have the original Punisher mini and others as well as the 1st awesome B&W Portfolio. And many of the comics he did artwork on, even just some covers. Love his art. I had a nice copy of Amazing #129, but sold it back in '90 when I graduated High School to buy a motorcycle (Kawasaki Ninja). Along with a bunch of other gems I'm shamed to say and regret when I think about they're values today. In particular a mint copy of FF#48, a 1st print of TMNT #1, Incredible Hulk #181, Iron Man #1....
Instead of a used motorcycle back then, with their current values I could've bought a brand new car today..
