The Key to Profit and Pleasure

Here is another Pan Am wheel and this time it's about time. If you find yourself in Leopoldville and need to know what time it is in Peiping, then just turn the disc to find out.

This wheel measures just over four inches and was printed in 1949 by Slide-Chart Corp. I guess there was a booming knowledge wheel/slide chart industry at one time. I was born too late!

I love the side with the airplane. I do wonder, though, what the flying clipper ship's bells is all about. Did they actually ring the time? How could you get through the 51 hours to Singapore if some damn clock is waking you up?
