Maybe the drawing had been confused with another one since I'm sure I've seen the building in the drawing elswhere in Berlin.

The one filed here is not the actual Königsstadt-Carrée though.

The design as shown in the Wikipedia article (https://de.wikipedia.org/wiki/K%C3%B...dt-Carr%C3%A9e) differs strongly from the one shown here. Also the height of the building is 80m in constrast to 71m as shown here.
