Christoph T. M. Krause is an enthusiastic collector of old telephones. The Swedish design classic Ericofon or the "Cobra" has taken his heart by storm. Krause loves its futuristic design, its colours, the compact workmanship on the inside and, above all, the unusual arrangement of the dial plate. Whilst the vast majority of phones in the world start with a “zero” in the lower range, Sweden went a different way and started with a “nine”. Krause presents key data, the (patent) history, mythology, the special features of the extraordinary design, shows many colour options, reveals strengths and weaknesses and lets his readers look inside the Cobra. The snake shape of the Ericofon caused a sensation around the world in the early 1950s and will never be forgotten.weiterlesen
