One-Ninth Plate Tintype of Two Brothers, Circa Late 1800s, in Ornate Frame

This 1/9th plate tintype is framed in an ornate metal frame that has a patent date on the back of May 19, 1908. This patent is for what is supposed to be a hinged prop. I believe the bottom portion is broken off so that only the loop remains for hanging.

The tintype needs cleaning. Tintypes, actually made from iron, are susceptible to scratches from even the slightest of materials, be it a tissue or brush. Only pressurized air should be used to clean the surface, and it would be even better if a professional were sought out to clean this piece. There are bends in the surface of the tintype. I imagine they were made when the plate was pushed into the frame.

The frame, 3" x 2", has an ornate design on the front and is a case of sorts as evidenced by the back, which fits securely into the frame.

I estimate this tintype as being from the late 1800s based on the fact that this is a tintype (whose popularity waned around 1900) and also on the boys' clothing, especially the "Little Lord Fauntleroy" style bow.

Thank you for looking.
