And by John Byrne. This page is from FANTASTIC FOUR 258, Sept 1983. It took some probing of the long-term memory to recall precisely where I'd seen it.

Byrne did some great Doctor Doom stories and pin-up pages, in FF 236, Nov 1981
And 246-247, Sept and Oct 1982.
And in 258-260, Sept, Oct and Nov 1983 .
