This postcard, a victim of some greasy-fingered sort, was printed between 1908 and 1928, according to the Curt Teich dating number.  The “Old Fort Loops”, a site to see on Google Earth, are a series of railroad sinuosities around what is now Round Knob Lodge in western North Carolina  (35 39 10.64N 82 14 39.23W).  By the time this photo was taken, that train would have been bearing Southern livery (in the mid- to late-1800s, it was the Western North Carolina Railroad).  The “17 Points” means that the line could be viewed from 17 places at one time, or something like that.

All I could verify from web-based research was that the Southern Post Card Company did exist, but little else.
