I'm pretty sure that Havana in the 1950s was the most beautiful city that ever existed. The buildings are crumbling, but the architecture is breathtaking.
Just look at the gingerbread on this apartment building, which is pretty average by Havana standards.
Anyway, what's funny about this building is that one resident painted their portion and only their portion of the building in green and another resident did the same in blue. The rest of the building hasn't been painted in a while, probably since the 50s.
