Nice photo, this ... right? How much do you think it is worth?
It recently sold for $4.3 million dollars.
The next time you are by a rural riverside, see if you can take a picture like the one above. Don't be surprised if you don't find anyone willing to pay you the $4.30 it'll cost to print it out.
Seriously ... who pays $4.3 million for an easily reproducible photograph?
