Where to even start with this wall?  Che Guevera?  Yuri Gagarin?  Russian go home?  This is from a wall in Prague, a city that was ruled by a horribly oppressive communist regime for decades and for the most part the locals consider to have been devistating to Czech culture... I'm afraid I can't even comment... this wall is so perfect it seems fake.
Also... it's odd to me that it's all written in English.  Why no Czech?
