This key was created in commemoration of Gugliemo Marconi’s 125th birthday in 1999. It is the faithful replica of a Swiss postal key that can be seen gracing Albert Einstein’s work desk at the Patent Office in Zurich in this old photograph of 1901. The original design dates back to 1861 - but our recreation uses contemporary techniques that make this antique probably more enjoyable to use than the original ever was.
The base of this key is made by melting and casting phosphatized iron. As a result, no two bases will be identical, even though the overall shape and dimensions are ensured by the mold.
