Yeah I'm not entirely sure either. I'm fairly certain that as long as the contents of the text "Harmy Film" don't have any connection with Lucas/Disney and the typestyle is free or properly licensed (The one I used is "sf distant galaxy") and the stars element is royalty free, it should be clear. I've seen heaps of coca-cola themed t-shirts available and surely they're not all officially licensed. I suppose it would more so be an issue of calling attention to this lovely forum. Ultimately It's Harmy's call. Perhaps others could weigh in on the legal side of things?
