Although I have never heard them called that, I have Two prints on tin
of my mother as a baby (b. 1906) and her mother-so turn of the 20th
They are not like the tintypes that I have seen but seem to be much
better quality pictures printed on a convex tin about 4 inches across.
The back is closed but hollow. I have one which is varnished or
shellacked or something and one which is matte finish.
