Frank Bender - a forensic artist. He gave identities back to the unidentifiable dead so their killers could be brought to justice. He also recreated killers with an aged look so they could be found years after they fled justice.
David Hockney - This mural is made up of photographs. Even though the photos don't go together they still look really effective together. As I do photography I could take the photos, put them together and paint them.
