Matt_tieu aka Matchalk is a self-taught artist based in Paris. He has been drawing faces and animals since his childhood and has been in the streets of Paris since 2015. His approach is usually spontaneous and without special preparation, which allows him to adapt to the media he meets on his way. His faces adopt a neutral and peaceful posture, turned towards the passers-by, inviting them to take a step back on their daily life. He uses chalk to make his works, which gives an ephemeral side to his creations.
