J HullTom,
I found the two sheets listed on eBay. The seller was in central Maryland. He claimed to have found them in the floor of a house built around 1900 -- "under three layers of antique linoleum, on an old heart pine varnished floor." Given the other stuff he was and had been selling (a mishmash of, well, junk), he could have been telling the truth. Seems to make sense; the sheets are quite large but still have fairly sharp corners, and one sheet appears not to have been handled much at all.
Brian,
I'll try to get some better images up this evening.
