Started designing anniversary badges for my car in the UK In another topic and a Few people made suggestions for other cars. I think I'm gonna get an anniversary one for myself and depending on demand others can get badges too.
Might get all of these made as stickers.
Here's what I've come up with.

Need as much input and feedback as possible. Might make a Volf and jolf badge too. (I know the harlequin colours aren't perfect)
