The street art is quite well extended in the majority of the Chilean cities. The pieces in Antofagasta are characterized by vivid colors and social/political/environmental themes.
I remember that in Bogotá, mainly at La Candelaria, there are many nice an interesting murals. As far as Mexico is concerned I visited that country more than 20 years ago, at that time the street art movement was not as fashionable as it is today.
Any way in Prague you have the “John Lennon Wall”, this is one of the most famous and fascinating places of continuously changing street art.
