I don’t know who or what owns the copyright on this image.  If I get yelled at, I’ll take it down.
Anyway, this is the 1913 building that housed the first school in Kingsport.  To read more about this building and its history, click here.  Neither this site nor Wolfe’s book on Kingsport gives a hint as to why it’s called Oklahoma, or Oklahoma Grove, school.
Maybe Hank and Bev Oklahoma kicked in some seed money…
This image is in the University of Tennessee Volunteer Voices collection, with only the notice that, on the back, is “where Robert E. Lee school now standing”.

The above image and quite a few others appear in this publication:

It appears to have been published (Watson Lithographing) as a 1967 50th anniversary promo piece by the Chamber of Commerce (not mentioned in the booklet).  Nothing is copyrighted and no photo credits are shown at all.  It is a standard 8.5″ x 11″ size. Great pictures, though (I can see where I live in this cover photo).
