NYT has an interesting feature on the flag from Fort McHenry that was immortalized in Francis Scott Key’s “Star Spangeled Banner.”
I saw it a few months back when touring Smithsonian’s Museum of American History. I’m afraid there’s not much left of it at this stage. “Protecting” it by not letting the public see it strikes me as utterly pointless and, unfortunately, even the resources of the Smithsonian don’t seem adequate to restore it to its former glory.
