What am I allowed to put in an ad?

The sky is the limit… within limits. We want you to feel free to express yourself, but let’s not break any laws. Specifically, Travertise will not produce, install, or exhibit any advertisements which are violative of local, state, or federal content regulations, which infringe on any intellectual property (state, federal, or international), which are tortious (i.e., slanderous, libelous, etc.), or which are obscene. Travertise reserves the right to refuse to produce and/or install any advertisement which it feels may violate this or any other standard, law, regulation, ordinance, or statute. Other than that, go to town.
