@folsom_lives - No non-fill issues with the black variant if you see one to pick up.
Back in my record hunting days in Southern Illinois I never came across an original of this one. Probably wouldn't know what it was if I would have seen it, though.
I do think it is interesting that
one of my private press records was recorded in the same studio in West Central Illinois, Golden Voice Recording Company / Milam Audio Corporation.
That original record doesn't go for the same price as an original of this one, though.
