Car Show Signs- what’s cool? what is lame?

I thought about getting a sign for my car for car shows.
Anyone had success with one of the many vendors for these?

What do you find interesting when you see a sign in front of a car?

I find signs that are big and hide a view of car irritating.
Having signs that can blow over (outside) are an issue.
Signs that include many photos of the car that are 3 feet away seems like redundancy.
Some people include lots of words..stories..details. Where do you draw the line?
