1939 pocket calendar - colourized reference pages

1939 dated, softcover German pocket calendar, which appears to have been given out by a bank in the Eastern German city of Plauen (Girozentral Sachsen is printed on the front cover). 180 pages, including a daily calendar for 1939, as well as many pages informing the reader of the prices of stamps and postal services, the prices of railway tickets (2.5 Reichsmarks for a 300km trip in a 3rd class compartment), the population of the world’s biggest cities (Toronto is on the list with 628 000), traffic regulations and, most interestingly, 14 colourized reference pages of rank insignia of the Wehrmacht, the NSDAP and many Third Reich organizations (SS, SA, HJ, NSKK, RAD, etc). The booklets shows wear and age, but not missing pages. A few notes written in some pages.
