On May 2nd, the Zweites Deutsches Fernsehen (ZDF) presented newly found material from the so-called "Canaris-Archive". Canaris was the head of the German Secret Service during World War II, and "maps from the Swiss General Staff" were shown on TV as proof that "Canaris had known the Alpine fortress [the so-called Reduit] like the construction of his own house". Three maps were shown as proof for that claim. A careful review of the source showed that two of them date from 1975 or 1987 respectively. The first one could not be identified so far. Due to the name "Lake of Geneva", it must be either an English or an American map. A total of 8 screen shots were digitized, from which four are presented here. Who can give us some details of the requested map? Thank you in advance. Please excuse the bad quality of the video pictures.
