Unknown Confederate Lt. Colonel at actual size

The tax stamp tells us the photo was taken between August 1864 and August
1866. One possible reason for the photo: It might have been taken after
the war of a former Confederate colonel who visited Baltimore. For the photo
he put on his old uniform so he'd have at least one photo of himself in
uniform. Any other possibilites?
