Mark’s hair

I just noticed this after seeing a post about Mark’s bangs, and realized that he kinda (more than kinda) looks like this character in one of the paintings that Milchick received from the board. Was he a part of the Eagans’ history?
We have understood throughout the show that Mark has a significant role in whatever Lumon is doing: -Ms Cobel insisting on him finishing the Cold Harbor Also, it wouldn’t be the first time that one of the MDR employees turned out to be of greater significance than we thought ( Helly being Helena Eagan = the daughter of Lumon’s CEO) If it really is him in that painting, then it raises the question: how is he still alive now?? The answer would have to be something related to the work they are doing inside the company( not sure about the role of each department but in general ) Let me know what you guys think! And please try to enjoy all of the theories equally ;)
