Hedy Kiesler Markey G. Antheil US Patent 2292387 Large Clock
Let others know of one particular woman's contributions to our modern wireless world with this "Secret Communication System" clock featuring U.S. Patent 2,292,387 as filed by Hedy Kiesler Markey and composer George Antheil. Markey's and Antheil's frequency-hopping system was designed to jam radio-controlled torpedoes by continually changing the radio signals sent to them. This system, similar to how piano rolls work, shares some concepts with modern spread-spectrum communication technology as used in today's wireless telephones (GPS, Wi-Fi, and Bluetooth). Let your technological pioneering spirit shine with this clock!

Great style, perfect colouring & good quality. I absolutely love it. Definitely recommend it for those that have the marble/grey & rose gold colour schemes. Looks classy not tacky at all. the printing was perfect.

Wall Clock, 20.3 cm Round Acrylic
Zazzle Reviewer Program
The wall clock it's very modern and look very good in my kitchen. The quality of the product is very good.
The only problem I have is that I thought the wall clock was going to be a little bigger, since I order the large clock, for me this was just a regular size clock .
I can imagine if I had order the small one. but besides I'm happy. The design of the product was great and the quality.
