Christoph T. M. Krause lives in Cologne, Germany. He is a passionate collector of old telephones. The Drum Dial has taken him by storm. Krause loves its design, colours, compact workmanship in its interior and most of all, its unusual way of dialling. Almost all telephones of the 1950s are equipped with rotary dials, but Siemens broke new grounds with the Drum Dial. With the help of considerable background information and colourful images, Krause presents the reason why this happened, if this new concept became successful, how long it worked and how the telephone is constructed inside. Let yourself be swept away into a time that seems to be gone and forgotten.
