About a week ago or more, a message was posted about a 1st National displayed in the background of a promo for an upcoming Antiques Roadshow. There was speculation that the writing on the center white stripe might have been "Cherokee Braves".
This flag was finally displayed on the Hartford, Connecticut episode 2 show last night.
Here is a direct link to the part of the program about this flag.
