I recently went to the Charleston Museum. They have an American flag that they don't really know anything about.

I realize this is a long shot because a museum should have ample resources to figure out what something is. But I'm curious to see if anyone here can give me some information about this flag.

The flag has 5 stripes with red on the top and bottom. It has 23 stars, which should out it around 1820-1823. The flag was donated in 1923.

I included a picture of the information card next to the flag.

And don't worry, the museum asked photography and I didn't use my flash.
