After some sleuthing, I have determined that this picture was taken in Junction City, KS most likely sometime between 1946 and 1955.  

I also found that Fort Riley in Junction City was home to the 1st Infantry Mechanized Division and a frequent stop of General Wainwright.  If you can see the "Eisenhower Drugs" sign behind the front tank, it was run by Dwight D Eisenhower's brother, Roy, and then Roy's widow after his death. 

I'm pretty sure my uncle took this picture because he was a photographer in Junction City for decades and this is an 8 x 10 print, which would have been a luxury back then.  There's also a possibility that his wife is on top of one of the tanks, but I can't be sure.  Purely conjecture on my part.
