As the planefags have pointed out, there are two planes that are used with the call sign AF1. These planes can also be used for non-potus flights, as well. I doubt they take the time to swap out the glasses and napkins between these different types of flights.

All the above picture proves is that someone had the privilege of riding on one of these planes. As to who this person was, when it was, or why they were on it, well, we have no way of knowing.
