This was one of several illustartions done by request for Advanced Iron #64, the oldest Iron Man fanzine, currently published on the web. The Thunderbolts image was a composite of several single figures rendered separately. It was somewhat frustrating doing the referece search for these characters, as I haven't read the book. They each seem to have gone through several costume, and identity, iterations, so I'm well aware there may be some continuity issues in the composite above. However. I just went with the version of each costume I found the most palatable.
