Now, street artists are typically known for their secrecy. Banksy, for example, would rather have your eyes expunged than let you know his real name.
But for Jana & JS, they pride themselves on their transparency. The pair are so upfront about their identities that you can actually see them both in many of their work. Oh and Jana & JS are their real names.
The two artists can be seen on various street corners and derelict buildings, taking 'pictures' of unsuspecting passers-by. Their work lies in various European cities, including Paris and Madrid.
