VW Dealer Calendar German Autohaus about 1960

Vintage VW dealer calendar from German Volkswagen Autohaus Elmshorn Gmbh. The calendar is in good condition, complete with all pages and the size is 33x25 cm. About 6 pages have pen notes, see for example the notes at the VW convertible beetle page. The calendar is about for the year 1960, but I could not find a date. At the pages are the VW Beetle, Bus, Karmann Ghia and Type 3.
