Trivia: Guess the artist

There's a big market for celebrity art. Most of it is mediocre at best, but it's still good fun to watch. So, here's the question: can you correctly identify the authors of the three works featured above this post?

Here are a few clues:
1. The first piece is an attempt at designing a brand. I would like to hope that it's the first, aswell as the last, attempt from this artist.
2. The second piece has a very british-bording-school-feel to it.
3. The third piece is, not surprisingly, made by a man who has left his youth behind him some years ago.

The correct answers will be coming up tomorrow, together with credits and sources.
