Billy has seen several prize fights where companies paid boxers for making temporary tattoos that advertised their brands. The man decided to go a bit farther and offered his body as an advertising area for permanent tattoo ads. Presently 16 websites have paid to place their advertisements on Billy’s body, and “The Human Billboard” is ready to make at least 30 more tattoos. The prices of ads vary depending on their size and location and reach $20,000 for a forehead tattoo.
