Long, dark hair, a red dress, a sad look - who is this mysterious girl? And who is the artist who has sprayed this motif on various walls in Mainz since 2003? Maria's clothing changes very time, but it is always colorful. Her facial expression, however, hardly changes. She is "The sad Maria," "The sad Girl," or "La Mayençaise triste." It is unclear, who her creator, the artist Maria M. Fantasma, is.

Years after her appearance, Maria in the courtyard at Boppstraße 38 is now flanked by a one-eyed, cheerful, blue alien – he seems to be raising his arms and demanding a hug. Could he make the sad girl smile?
