Yesterday I purchased two photo portraits of an elderly man and his wife. They were in frames that I am sure also date to 1862. They were of amazing clarity. They were rectangular (back) but with oval viewports (front). Size approximately 6" X 8" and the view about 4" X 6". The lady's frame was untouched with square retention nails and a wooden backing. The man's wooden backing was nailed with large nails and had been fooled with at some time. Also the glass was missing. I removed the nails, the wooden backing, and the portrait to replace the glass. I was amazed that the portrait was composed of 2 sheets with images and a paper backing. The material was akin to onion paper. In putting the portrait back into the frame I found that the two images had to be exactly aligned to yield a sharp clear picture. What was this procedure called? The photos were made in St. Paul. They do have color. I have never seen such beautiful clarity in un-retouched photos. Can anyone tell me more about this treatment?
