Well, I think we now have proof that Bill Gates is not a crazed megalomaniac billionaire. If he was, he’d have had all copies of these pictures destroyed, and anybody involved killed.
Apparently these pics were taken for a magazine called Teen Beat, around 1985.
(Via Monkey Methods, whose commenters are debating whether it was 1983 as first claimed, or if the fact that there’s a Mac in the background means it must have been after 1984.)
Update 19-Oct-2005: Snopes says these were publicity shots taken for the release of Microsoft Windows in 1985.
