Loved this cover as a little kid, way back in the 70’s. Things have a strange way of showing up. I know where the original photo for the cover is as well as the round house in the picture are. This is a quick video of that photo and the round house below it. This is the real photo, not the cover. https://youtu.be/J-EZIDzPOSk?t=13m2s
The track arrangement on that cover made it look a little like a Yin-Yang symbol.

Very 1970’s. Once is enough.
