While visiting my father-in-law's brother, he showed me this photo of Thomas Greenslade Blackmore, in his store in Colorado, about 1897. I took this photo because I didn't have a scanner available. I believe this is in Rifle, Colorado.
In the future, perhaps some months in the future, I may receive the original as well as others. Therefore, if you are researching the Blackmore family in Colorado and would like to collaborate, please contact me.
