Wow, didn't see that coming!!
Do you own the print or just a photo of the photo?? The date of 1910 kinda fits with contemporary photos of number 30 on the Alma branch and number 59 in Gunnison.
And that looks like number 9, like in the photo I just posted, in the background.
BTW, how come
your vintage C&S photos come with dates on the back??
