I don't know but I sure appreciate seeing & reading this!
I enjoyed it like a tasty nibble.
I also notice his handwriting matches the handwriting on an envelope I own that he addressed to someone in Georgia in 1979. It's the letter "g"....same three "g's" on the envelope...His capital "g" is but a large version of the small form. I have it framed and on the wall next to my writing desk here.
