Answer, (as usual) it depends.

Yes, (possibly) United States copyright law or state moral rights laws.

For copyright purposes, sale doesn't matter.

You may have violated copyright law if you have created a derivative work
of art. The wrinkle here is that you've used the original, and not a
copy, but I suppose this is the equivalent of making an identical copy,
alterning it, and destroying the original.

Whether the altered work is a copyright violation depends on a number of
things, including whether the original was under copyright, whether you
have the artist's permission, whether you're engaging in parody, etc.

In addition, there are so-called "moral rights" laws that protect an
artist's interest in preserving his works as they were created.
