Street art is, by nature, controversial. To some, it’s vandalism and an eyesore. To others, it’s a great backdrop for their next Instagram shot. But to the artists themselves, it’s their way to broadcast the social and political currents running through a city.

Who was it that said that being a street artist isn’t a serious profession? These guys know how to turn an ordinary brick wall into a door leading to another dimension. That kind of work doesn’t go unnoticed and for good reason.

Here are 27 examples of truly outstanding street art from around the world that seemingly remove the border between the real world and the imaginary one.
