Charlie - Oh, I'll be posting it and the other art I got at the con soon.  Have to take care of some post-con real life stuff first, and then get down to business of scanning them.  Got one piece that I have to wait until I hear back from the artist before putting it online. 

I do have this one ready, as a counterpoint to your Iron Man... ;-)

Dr. Doom by Bob Layton. 

Bob was quite happy to have someone finally ask for Von Doom at the con.  Also interesting that he told me that he's got a box full of con artwork that people paid for, but never bothered pick up...

Edit - Forgot to add:  My first Doom commission!
