I saw a flyer on the ground today which may help explain Mike's obsession with this object: 2006 is the "Sigmund Freud Jahre" in Germany.

Meanwhile, I notice there's also a ghostly Internationale Handelszentrum on that stamp. What a weird choice.
 

It's not *Mike's* obsession that's the topic here; it's East Germany's. Oh, and West Germany's way of ignoring said object.
 

Hell, the DDR was obsessed with it because it was the only piece of modern architecture they had that worked. That and the Messe in Leipzig. Long step down from those to the next-best.
 

Here's a good shot for your fetish collection:
