2015 has been declared by the United Nations as the International Year of Light. Illuminating this subject with the light of the cartoon seems one of the best appeals to the artists of humour. This theme can be used to show also many inequalities that exist worldwide. The light of the sun and moon is the same for everyone, but other lights, electricity and all that goes with it, are the reason for darkness in different parts of the world. In addition to participating with cartoons on the main theme, the cartoonists can also send works for the Free category and for two Caricature Special Awards: • Portuguese football player Cristiano Ronaldo • American writer Ernest Hemingway (1899-1961) Works must be originals and any kind of graphical technique will be accepted, including digital artwork.
