El Eternauta

Argentina's iconic science fiction hero, rendered in cold monochrome and holding a single flower against the void. Sprayed two metres wide by 2.5 metres high in Buenos Aires, Argentina. El Eternauta, created by Héctor Germán Oesterheld, is one of the most recognised figures in Argentine comics, and the mural keeps his snow suit and mask almost colourless so the flower is the only warm thing on the wall.
