My theory: It's NOT a celebrity.

Perhaps it's some unknown guy who was part of the entertainment industry for some time, but vanished with most of his/her works becoming outright lost media with barely any information about them on the entire internet; even going onto the Wayback Machine would deem useless with literally no results of any of his/her works. The works are THAT obscure, though even that might be a huge understatement in itself.

Essentially put: He/she put out a few works at some point; none of his/her works sold well at all, quickly disappearing as soon as they got released; He/she never got any fame within the industry, nor anywhere else; He/she was not even that well known of in any of the schools he/she went to, being the kid just about everybody ignored; He/she would then just vanish out of thin air for seemingly no reason at all, & this image is perhaps the only thing that remains of that person outside of the very, very, VERY few bits of his/her works... if anyone could even FIND those that is.

Like I said, this is probably the only image of the guy still around, & this would mean that the person who made this image probably had a picture of him lying around in his house, & he doesn't remember where he put it. Even if we do find the photo, we might never be able to find the person because, like I said, he/she's probably just some random individual that released some ultra-obscure works, then vanished without a trace.
