About This Design
Hedy Kiesler Markey G. Antheil US Patent 2292387 T-Shirt
Let others know of one particular woman's contributions to our modern wireless world with this "Secret Communication System" tee 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 tee the next time you surf the web!

My Clan Graham is high quality garment and its history even more important, Clan Graham fought for the right to wear kilts and won. Clan Graham, Duke of Montrose are advisors to China on renewable energy.
Heavy duty Cotton. The design and colours are superb, I feel very proud as a Graham descendant from Appleby Westmorland Cumbria to wear this especially when wearing of patches is banned in Aotoearoa - New Zealand.
Kiwis wear all black as the t shirt is with Green lettering to match the environment and yellow for joy and purple thistle to match my hair.
The wardrobe police know who my Clan is now !

The tee shirt was of good quality and the photo true to original. The printing was just fine, as usual.

I loved the T-shirt, it is exactly as I designed with changes, the right size and colours, and I am awed at the speed of delivery to NZ in 17 days right before Christmas, thank you so much. My sister loved it! I chose an existing design and added one or two personal details. Adding elements was very easy and straightforward, choosing colours was easy. The colours were perfect, all the right size and style lettering
