Mentalgassi is an anonymous German Street art collective, internationally known for their use of large photographs —usually portratits— pasted onto walls or any kind of urban furniture. Mentalgassi’s focus has primarily been on urban life, however, one of their pieces was installed by Sybaris in a residential property in Miami, Florida, giving the work a conceptual shift. The new space for Girl with Balloon take the piece to a more private atmosphere where portraits are commonly placed.
