How to get free tomato soup

1. Be an artist.

2. Paint a can of tomato soup.

3. Become famous – perhaps even more famous than the soup. Perhaps even as a result of your painting of said soup.

4. Wait for the soup company to write you a letter with the offer of free soup.

5. Accept the soup.

That’s pretty much what Andy Warhol did.
