I know of a dealer who had an 1800s 'cloth tintype,' a tintype on a swatch of cloth instead of metal. The only one I've ever seen. I'd read they existed so knew what it was when he sent me a scan and described it, but had never before seen one. He had troubles selling it for a fair price because buyers had no clue what it was. I recommended if he didn't get a fair price to donate it to a museum.
