I guess you know by now that I like graffiti, since I’ve posting many examples of street art on this blog. I don’t like all of it, in general I like it if it’s witty or it has some sort of message, be it cultural, social or political. But in case of today’s example I have no idea what the street artist was trying to express here. I can say that I like its colors and that these look to me like some sort of hostile aliens. What do you think the artist was trying to say?
