Will update with more details later, but for now, read the descriptions of the people depicted and an interview with the artist here.
So far, my favorite mouseover descriptions:
Reagan as “a true patriot of freedom”. WTF does that even mean?
Thomas “Payne” appearing in this painting, even though he wrote a whole book ridiculing organized religion.
The Schoolteacher looks like Sarah Palin.
The “College Student” is holding a copy of “The Five Thousand Year Leap.” A book by a notorious Mormon Crank about how America is awesome because God is an American. (Seriously)
No executive branch depicted, because Jesus IS the Executive Branch.
Dolly Madison looks like Ally Sheedy.
the Fifty Stars and that they stand for the fifty states? Some stars burn more brightly than others. “Real American” states like Texas and Georgia as opposed to elitist, faggy states like California and New York.
And the only two people without description are “Satan” and the “Business Woman”. I guess the nature of those two abominations to American Culture speak for themselves.
UPDATE: Presented without Comment.
