I think this may have been an actual official add put up by the club...

Yes it Was! This is another picture tweeted by the official BVB account, entitled "Good morning, London!"

gotta love these guys lol

Sherlock Holmes is apparently a Dortmund fan :)

I like the last pic you posted the best. Honest fans to thank England for inventing the game of football. :)

Okay okay, let's not get into an argument here about who invented football first. England hosted the first official game, so let's just give them the credit and end that discussion. ;)

wtf i dont understand what this is????!!!!

Damn Krauts. ;)

Altogether now: "Two World Wars and One World Cup, do-dah, do-dah..."
