Seen in Aruba

This is a picture of a jewelry display case at an expensive shop in Aruba's capital. Here are my questions:

1 -- How does an Eagles baseball cap help sell high-end jewelry?
2 -- Is it worrisome that they couldn't find an Eagles' helmet, only a cap?
3 -- Is it worrisome that they paired it with WVU and UNC helmets?
4 -- Is it possible that someone will buy a necklace and that hat, and wear them both walking out of the store?
