Also, Cold War era maps of the Berlin U-Bahn, from the West and the East. It's interesting to note the differences in graphic design and what information they contain. The West German map is neutral and businesslike, though shows both lines in the West and the East (though the Eastern lines are uncoloured). The Eastern map looks superficially more colourful and friendly (much like the jovially behatted Ampelmann compared with the standard capitalist traffic-light man), but shows only East Berlin; the forbidden capitalist enclave behind the "anti-fascist protection barrier" is terra incognita.
