The B&M I made myself. It's pretty corny, but I still like it. I says "B&M" across the front and has a list of most of their major coasters (pre-2001) down the back side and a big "Bolliger and Mabillard" on the back center.
http://www.cafepress.com/iwall The "AS" tshirt is for some dumb website my friend used to run. The "B&M" one is actually pretty good quality, although it has faded slightly.
**Note -- what I did is umm... sort of illegal, I think. I didn't ask for B&M's permission to use their name. **
The Arrow Dynamics shirt I have as the Arrow "Loop A" and says "Arrow" directly beneath it.
