I found this block in San Telmo, Buenos Aires by accident, just walking around exploring. A turn here, a turn there and there it was. A whole strip of brightly colored art covering the walls. And there was this perfect blue door waiting for me to jump in and take a picture with. I walked away with no recollection of how to get back to this spot but luckily there was a lot more of it around every other corner. I love this town :-)
