I just saw the Beauregard/Cary flag a few days ago while crossing through Louisiana. It's currently at the Louisiana State Museum in Baton Rouge, across the street from the State Library. Sadly, it's the only Civil War flag on display. I also went to the Cabildo in 'Nawlins' later in the same day. They have a First National flag of Fenner's Louisiana Battery on display. It also is the only flag there. Hope this helps.
