As I said in the previous post, that is the SLATE from show #1, which aired 9/4/72!!!!!
Toned-Down Edit: If you clicked on the link that I provided, you'll see the image of a screengrab from Show #1, the same show that is on the trading circuit. And it was taped 8/19/72. I think in May the show was still being hashed out by the G/T staffers (just a educated guess on my part).
