We like the caption on this Curteich-Chicago linen card 5B-H1296 (C-2590) so we will repeat it here as yet another example of how so many postcards want their topic to be “…est” of all:  “Highway No. 10 winds around the Rocky Mountains over the Continental Divide.  Fifteen miles away, in the background, is the Richest Hill on Earth and a glimpse of Butte, Montana.”  So there you have it.  Unused.  Grade: 1
