Sports team merchandise is part of a multi-million dollar industry, and the merchandise usually features a team's logo. While some people are content with collecting cards, t-shirts, magnets, jerseys, and caps or helmets, others take things a bit further and get sports tattoos. Some are even willing to pay a lot of money for a large logo.
You do not have to get the exact logo. You can have it customized however you want. This is a good idea if you want something unique. Sports tattoos are more than just team logos. You can get any tattoo if you want, and then have it filled in with your favorite team's colors.
