1931 pocket calendar - SPD party / organization

German pocket calendar, hardcover, for the year 1931, distributed to people affiliated the SPD (Sozialdemokratische Partei, a center-left popular political party). Unused booklet, 128 pages, nothing written inside. Quite a few pages on the addresses of local branches of the Sozialdemokratische Partei and organizations affiliated with this political party. Several pages on the cost of postage and addresses of prominent museums, as well as a very interesting page with the results of the Reichstag parliamentary elections of 1928 and 1930. The SPD held the largest number of seats, the Nazis having jumped to second place after exploding in popularity in the 1930 election. The caption "Was nun ? / What now?" is a little ominous, given how the Nazis took power two years later.
