I can offer some assistance. You can't find out who complained. You might be able to find out if others have gotten similar tickets. It might be a case of the local inspector cracking down on a productive neighborhood.

That being said, I am not at all sure that the tag is legit for parking a truck in your driveway with a work logo on it. I just can't see how they can justify an ordinance prohibiting signage on parked vehicles. The First Amendment protects commercial as well as political speech. The First Amendment also carries a concept known as overbreadth where a law or ordinance isn't enforcable against anyone if it is overly broad in its application to some people.

In other words, the ordinance is invalid if it would prohibit people from posting constitutionally protected signs, such as "support the troops" or "no blood for oil" (see how nonpartisan my analysis is?) if they posted in the same manner as your company logo.

I recommend contacting the city to see who prosecutes tags like this. Just call him up and ask him gently how the city can get around the First Amendement in banning vehicles with company logos in the neighborhood. When he gives you an explaination, just say, "Well that's nice, but how do you get around the overbreadth problem?" Tell me what he says and I'll tell you how to respond from there.
