My experiment regarding the removal of the paint from the paper was unsuccessful. I even attempted it with alcohol and a couple of other things, but nothing worked. So the last image I posted of the stamped word is going to be as good as it gets.
Regarding the date of the photo, I honestly think it is safe to say it is circa 1880, with 1870 to 1890 being the full date range. I base this on a number of things, including the following ...
After very close eximination of the top paper itself, I am of the opinion that it is "Albumen" print. It is as thin as today's standard copy paper, and then adhered in some manner to the cardboard backing. Below is a link to the history of Albumen print, which was at it's peak use between 1860 and 1890.

As for the process of hand coloring photographs, it too was popular during this same time period. It's history can be read via the following link.

I realize and appreciate that discovering the studio - photographer and artist who produced the finished photo would be great to know, but I also feel that if the person pictured is not someone famous, then our continuing efforts here may be in vain. And as much as I appreciate everyone's time and interest in this topic, I'd really feel bad to come up empty handed in the long run. So please don't rack your brains too much, as I am almost at the point of calling it quits myself. If in time the person is identified by a TN member, and it turns out to be someone famous, and I sell the photo, my offer to share the proceeds still stands. But that possibility appears to be getting dimmer and dimmer by the moment. Who was it that said "one picture is worth a thousand words?" In the case of our mystery man, it seems to be the other way around.
Despite my words above, I am not disappearing just yet, but please anticipate my participation here to be on the wane. Unless someone has more to add to this, I really don't know what else to do ... and I full understand the disappearence of those who proceeded me.
Thanks again to all.
