Kaiser Aluminum Telescope

What do you do when you see a big aluminum telescope at Disneyland? Why, you don't just look through it, you walk right into it!

Here's a scarce photo (from a stereo slide, no less) looking down the barrel of the 'scope itself. The entrance is at the far end (obscured by the blinding flash), you made a hard right as you entered. Our photographer is standing with his back to the magnificent displays that demonstrated the myriad ways that aluminum embiggened our lives.
