Those are the flags of the 1st Veteran Army Corps (Handcock's). One in the same, Handcock's Invalid Corps. Not sure on Veteran Reserve Corps, I don't have a listing in the Official Records for them. I'm thinking they are the same but just not sure at this time.

Yes you can use the pictures, they are open source stuff but a little research credit would be nice.

Happy Trails!
