I used a program called Glass2K to make Google Earth transparent and then overlayed it on the image. I had to make the Earth appear about 20% bigger in Google Earth than in the image to make the continents line up. When I zoomed in, I was over a point just north of a town called Blossom, Texas: 33°41.800' N, 95°22.415' W.
In the lower right corner of the attached overlay image, you can see an "eye alt" of 19,111.43 mi. However, this is meaningless because if I had zoomed the image in or out I would have had to change the altitude in Google Earth.
