Description: Doctor looking into man's mouth.
Comment: Any fan of Frost will understand why this is a great example even though it's a little hard to quantify what's great about it. I think it has to do with the subtlety (or understated-ness) of a very non-subtle situation. With the flu going around seemingly everywhere right now (and certainly in Casper), this image may seem all too familiar to many. Looks to me as though Frost used himself for the figure of the doctor.
Price: $1,500 (including domestic shipping)
