You blind?

No, but you're badly informed.

You blind?

No, are you willfully ignorant? Or is it possible that you are not aware that there were two units called the 1st Louisiana Native Guard? There was the short-lived Louisiana militia unit formed in May 1861 and was denied service in the confederate army. It was ordered disbanded in February or March of 1862. The second 1st Louisiana Native Guard was raised in September 1862 and incorporated into the Union Army where it was later re-designated 73rd USCT. The picture is of black soldiers wearing obvious Union uniforms - especially Union winter overcoats. I doubt overcoats were in much demand in Louisiana.
