You may have seen a version of these floating around which looked to be promotions for The Smithsonian Museum. They are in fact a series of self promotional work from the team at An Erratic Perspective. The Smithsonian Museum reference was initially included to make the posters more authentic, but removed to avoid confusion after the posters viral popularity on the internet. In any event, the series deserves a mention.
