Post SG Danzig
Post SG Danzig was a German association football club from the city of Danzig, West Prussia. It was the sports club of the city's postal workers and used the colours blue and yellow traditionally associated with the post office. In the early 1940s, the team was part of the Gauliga Danzig-Westpreussen, then one of the Germany's regional first division circuits, where they earned only lower table finishes. SG was active until September 1945 and disappeared following World War II when the city became part of Poland.
