I have an idea for a T-shirt line/Foam Finger line. I've already copyrighted the logo(with a generic color scheme). Now my line will change the color of the logo(a hand) to match the color scheme of each team. My t-shirt/foam finger line would still have a market without the team logos, such as high school and college teams that happen to use those colors. But if I could use the official NFL team logos, it would make my line more marketable. Licensing the team logos is out of the question due to financial constraints. But is there a way around? If I sell my shirts/foam fingers and include a sticker(with a price adjustment to reflect the sale so the NFL gets their precious money)that can be applied by the customer later using little effort, would that circumvent the law? I mean, the NFL is still getting their money and I'm not selling the shirt using their trademark. I just happen to be selling two distinct items that would sell without each other. Are there any other threads about this? Thanks
