Monday's Postcard 2016: Crowns

These postcards are of crowns obviously and I think these are in the collection at the Louvre in Paris. The postcards were sent to me by a friend who lives in Illinois. With messages on the back about how their summer was going! I know my friend has not visited the Louvre and I know they have not been to Paris, so I don't know where they got the postcards, but they are pretty random and could have come from a museum gift shop or a bookstore.
