Just a note - I've designed this so there's nothing too complex in terms of printing. It can be cut from vinyl, screen printed - anything. It's all solid shapes that don't overlap. This is important in case you want to do some decals for your truck, trailer, helmet, t-shirts etc.
I wanted to design something that has a bit of retro coolness (since the sport has been around for so long) but also a modern grunge edge to it.
