I have a desktop background photo from the very early 1900's... it's of a copper stamping mill that was not so far away from where the article is set. However, in that image there's a "ghost image" that was on the original plate that you can faintly see.
I couldn't resist and ended up finding an online source for the actual image that was ghosted onto the plate that was my background: http://www.shorpy.com/node/11417
And then I couldn't resist finding out if I could find that location in modern day Google Maps.... and I did! The details I posted in the shopry.com link.
It was an interesting divergence for a couple of hours and I learned a fair amount about the area the article is talking about and the town of Calumet, Michigan which the photos in question document.
Ah, the modern age...
EDIT: I see that I didn't post anything about the background image with the ghosted impression on it back then when I commented... I just found another link to that (perhaps not surprisingly from shopry.com, http://www.shorpy.com/node/15713, though that's not where I originally found it)
