I'm not a fan of car stickers. They tend to suggest a certain self importance on the part of the owner which makes me want to edge ever so carefully into their bumper. So in the interests of keeping it real, here's the only sticker I'd feel happy to apply to my own car - if I still had one.
The adhesive is on the front so it can be stuck to the inside of the car facing out. However, this makes the film transparent. So I've attached a white background to it, so the yellow stays punchy.
