I hope he did his homework before embarking on his project.
If some .gov type takes exception to the artist then it is a Federal crime to deface currency

Quote:
“Defacement of currency is a violation of Title 18, Section 333 of the United States Code. Under this provision, currency defacement is generally defined as follows: Whoever mutilates, cuts, disfigures, perforates, unites or cements together, or does any other thing to any bank bill, draft, note, or other evidence of debt issued by any national banking association, Federal Reserve Bank, or Federal Reserve System, with intent to render such item(s) unfit to be reissued, shall be fined under this title or imprisoned not more than six months, or both.

Defacement of currency in such a way that it is made unfit for circulation comes under the jurisdiction of the United States Secret Service. The United States Secret Service web address is www.secretservice.gov.”

Now when the next owner demos.....
