I've been asked about using trademarked logos on my mugs, but after inquiring at several local shops and weighing the information I found when looking into it, I felt they (the shops) were refusing to work with with a "trademarked" logo from their past experience and I couldn't become comfortable with the idea. One shop was sent a letter to stop selling shirts (from a law firm that represented the Olympic Organization) when the owner used those rings from the Olympics signs with something written about their tourist town under them, not anything the official Olympic organization wrote or used. This was a pretty small shop in the Northern part of Michigan. I guess it's just hard to tell what they'd do. In the end I felt for my time and effort, I could never come close to repaying myself (so to speak) if I had to stop due to a cease and desist letter. I put my time and effort into things that I created or knew I could use (like the XF image from the luggage tags).
So hey want to buy a coffee mug with a picture of your Crossfire on it? You can personalize it- a picture of you and your car on a mug,
