So why is this controversial?  I'll give you 3 guesses:

1) She's naked!!  Oh the horror!!  (Incorrect.. it's 2014.. c'mon)

2) A historical document was superimposed onto a naked woman's body? (Closer.. but still no)

3) The historical document is the U.S Constitution.. and is signed by John Hancock at the bottom.. which is a historic inaccuracy.  (NAILED IT!!  John Hancock signed The Declaration of Independence.. not The Constitution)
