Murals from the ‘Walls Have Ears’ collection were painted between 2012 and 2021 in Tehran, Tabriz, Istanbul, Izmir and Jakarta. Most of the paintings and walls in this collection refer to MAD's life in Iran and its effects on his worldview. As a street artist he tried to express his feelings by combining critical social and cultural commentary with a dose of humor and metaphor, war, peace, freedom and humanity.
