Billboard defaced?

Thought this is quite funny. A billboard was defaced with some simple rattle canning. But in another P.O.V. it could be viewed as correction due to how most of us were taught back in elementary school.

Here is the news report where I’ve found the photo. I still have yet to read it. I just simply saw the photo and thought it was hilarious thinking both P.O.V.’s.
