From the back of the above left post card:

"Will Rogers Shrine of the Sun on Cheyenne Mountain overlooking Broadmoor and Colorado Springs, Colorado. This tower is one of the most unique structures in the world. Built like a medieval castle, it is all metal and stone -- no wood enters its construction. A Beacon light burns perpetually in the tower. Murals of the early day West and of Will Rogers cover the walls of its interior."
