Found black leather passport holder near beach access point at South Beach, Miami, possibly containing travel documents.

I found a black leather passport holder near the beach access point at South Beach, Miami. It seems to have some small wear marks, but it's in otherwise great condition. I'm guessing it was left behind during a busy day at the shore. There might be important travel documents inside since it feels stuffed. If you think it belongs to you, please describe the contents so I can make sure it gets back to the right owner.
