I have seen the models on the engines and the books on the seats. I don't think it is a problem to display that stuff. If you are concerned, call Carlisle events for a confirmation. I am sure you can put it out around the car at least. I have seen boards describing what is in the cars, and I myself used to have windshield displays and a book of what was doen to the car and no one told me to get rid of it.
