From Sarah, Lipstick Underground (one of our illustrious and industrious Read My Lipstick Members):
I heard back from Dunkin' Donuts.. They say they never issue Obama cards...but folks can customize their own, so that is how these came into existence. Considering the artist is all about propaganda, he probably made it easy for folks to use the image for this sort of thing.
Thanks Sarah! Much appreciate the follow up and info.
