My fragile memory has once more failed me on this.  Obviously American Dream is a Rule 63 interpretation of Captain America, but I don't recall whose design it was (it's not mine - - I would never have dreamed up those boots, effective as they are) or why I drew this particular picture.  Challenge?  Request?  Don't recall.  Sorry.

But it does prove that some male characters work under Rule 63 and some don't, and Captain America is one that doesn't.
