Any fool could come up with a Flashlight/Telescope combo, but it takes a true creative genius to add the drinking cup.
Flashlight, 5 Power Telescope, Drinking Cup—All in One
IT’S a flashlight, but take out the batteries and it’s a telescope. The combination instrument, now on the market, has several uses for the camper. As a flashlight it has a focusing beam. The front lens can also be used as a sun glass to start fires, while the eyepiece is a good magnifying glass. Included in the tube with the batteries is a small drinking cup. By removing the batteries, bulb, and drinking cup, the camper has a fair five-power telescope. The instrument is built to provide for an adjustable telescope for varying distances.
The funny thing about this ad is that “NASA Space Telescope” was the original name of the Hubble Space Telescope and Perkin-Elmer is the contractor that delivered a flawed main mirror, requiring a very expensive and difficult repair mission.

The NASA Space Telescope: Getting ready for the clearest look yet into space

However, a number of our disciples have evidently gotten just a bit tired of this ambulatory procedure and have written to inqure whether there exists a more satisfactory and sedentary method of grinding said telescope mirrors. There is. As a matter of fact a number of such grinding rigs are described in Amateur Telescoping Making edited by Albert Ingalls.
