Both of these soft-cover books (8 1/2″ x 11″ each) are quite interesting. “Wings Over Kingsport: Tennessee’s Planned City And Its Industries As Viewed From The Sky” by Richard H. Alvey was published in 1938 and “Wings Over Kingsport No 2: Tennessee’s Planned City & Its Industries As Viewed From The Sky In 1938 and 1963” came out in 1963. The 1938 edition has 63 pages; the 1963 one, 98.

I have a better copy of the 1963 edition, but this is the one that Mr. Alvey gave me after I interviewed him in 1976. (Yes, I can see where I live from here)
These are great fun to look through.
