Actually... there was an original like that. Apparent original box just like yours that I found on the web:
The following picture is from one of my an old Cowboy Chronicle article, probably at least a dozen years ago: Notice that the printing is a little crisper on that one you are talking about now. It was also slightly distorted, wider at the bottom, IIRC. I believe that label I may have bought from somebody off the web, but that is years ago. I was also a Civil War re-enactor with a Henry at the time, so I may have gotten it that way.
If you look closely at the label with the Henry rounds, it is slightly different than your current one, with rounded corners Apparently, someone else also recreated the original above.
I do not recall where on the web I got the label you say is yours (I am not saying it isn't yours, I am sure it is, if you say so!). It was out there, and did not have any apparent copyright when I found it on a google image search. I have actually shared it several times on CAS in the past years, but I NEVER claimed I created it.
I have had entire sections of my Cowboy Chronicle articles lifted, and published in others blogs and articles, claiming it to be there's. Yeah, it bothers me, so I understand. The fact remains, I DID NOT CLAIM I CREATED IT!
