The Old State House Museum in Little Rock sells a booklet entitled "Brothers in Arms: The Spence Family in the Civil War."
On page 31 of that book, there is a photo of the flag of the "Combined 8th and 19th Regiments Arkansas Volunteer Infantry."
The flag is about 80% intact.
It is a beautiful Hardee/Cleburne pattern with a squarish white disc in the center and a white border all around (one border being a white flag sleeve).
There are numerous, beautiful honors painted on the flag.
I cannot scan the photo for you because of copyright laws.
However, I'm sure you can still buy the booklet from the museum for a nominal fee.
Hope this helps! -- Jim Huffman
