Note the "socialist realism" style of the art.
Except instead of brawny proletarians with self-indignant scowls on their faces, you have steely-eyed, square-jawed, expressionless Aryan corporate robots. The "watchful eyes" poster reminds me of Dali, or Magritte.
Actually, I don't think the ones who commissioned this art had as much to do with this subtext as did the artists who worked on it. I think they were having a laugh of their own at the guv'nors expense when they put them together. Artists are such a subversive lot, and the really good ones do it without you even being aware of it, until it's had a chance to stew in your subconscious for awhile.
