Gentlepeople,
The picture was most likely taken in the U.S. midlands in 1865. The inscription on the back appears to read Link (a common male nickname for Lincoln, or Richard during that time frame) and Kristie ( a common nickname for Christine, Kristan, Kristine) Hence the " Link and Kristie '65". The background imaging is from perhaps a wedding of these two people. The writing and posing, along with the clothing being worn by both indicate such, as this was quite common in the 1860's in Oklahoma, Nevada, Northern Texas, Arkansas, Missouri, and Utah.
I have seen this quite often in my genealogical researches of the area.
