Mine are like Herb's except with a tan van on green leather (green and tan two tone seats). I've seen the SMB where the M is a road logo embroidered as well.
HOWEVER,
I feel you are missing an opportunity, if I do say so myself. You could have THIS instead:
Or any number of other bits of forum artwork I have laying around. I'll even work up something new as long as it has the forum or SMB4UM and we can share it with other members down the line.
Or, you know, be like everybody else!
