I found it in the Watnot Shop about 8+ years ago, when I was making my living selling collectibles on ebay, (and saving my pennies to buy a house here in Hudson.) Subject-specific antique photos, such as this one of an old horse-shoeing shop--had the potential to bring hefty profits. This one, however, only brought about ten bucks.
That's not the sad part though.
The sad part is that about a month or two after I sold it, I bought my house here on 5th Street, and, after studying the leftover jpeg some more, realized that Propst Horseshoeing had been located directly across the street from my new home (a fact I confirmed by researching old directories in the history room at the library.)
The good news is that the buyer was someone named Propst, so it's hopefully stored safely away in a genealogical archive somewhere, not my messy cigar box filing system...
