Big murals - giant works of art covering entire house façades, often with a political message. In his book Icons of Street Art
, photographer Michael Harker demonstrates the special power and meaning of this kind of street art with photos taken in Berlin, Lisbon, Paris and New York City. His large-format pictures present the art of various artists, with one focus on the works of Bordalo II. With his Trash Animals
, the Portuguese artist draws attention to the subject of environmental pollution. His unique mix of upcycled sculptures and spray graffiti is in great demand at art fairs worldwide.
