Dyke Power and Reading Books Is Dangerous: Martin Firrell is a British contemporary artist known for public artworks on billboards around the world. He uses the poster form to campaign for greater social equality. His bold and simple texts address LGBT+ equality, the women’s movement, feminism and gender equality; and universal human rights. The artist's aim is 'to make the world more humane'. Firrell's billboards often resemble advertising because he hijacks advertising's techniques to achieve artistic-activist ends. This co-opting of commercial techniques and his wholesale colonisation of advertising’s oldest and boldest medium - the billboard - makes Firrell one of the most apposite and significant artists of the 21st Century. ~ Dr Robert Shelton.
