Spray paint is very hard to get in Cuba, so it was strange to see this little bit of wall graffiti.
Looking north over Havana's breakwater wall.
How many air conditioners can you spot on this high rise? I think this used to be a hotel before the Revolution 50 years ago, and I'm pretty sure the building had a central air system. As with many things in Cuba, the main system probably "died" long ago and has been replaced by individual air units as the people living there could afford them.
