What's in a Trademark?
At Promo Marketing, we have a "do not print" list. I keep it hanging in my cube, just beyond my computer and always in my field of vision. On the list you'll find things like Kleenex, Star Wars, Disney, The White House and McDonalds.
Every company that appears on that list is there for the same reason: they rabidly control and protect their trademarks, and are not afraid to use legal force to do so. Even if it's just an example of imprint capabilities, we will not publish an image of an item featuring one of those logos.
