This one looks more like a fireball than a snowball but when has Yayoi Kusama, Japan’s dotty conceptual artist, ever played by the rules? Snowball in Sunset is one of her early works from a series of drawings produced in Japan from 1953 to 1957. At this time she was just starting to explore her legendary dot aesthetic, as demonstrated by the obsessive repetition of unwieldy fields of dots in intense colours. This high-octane image of what seems to be a snowball with a glowing red and blue aura defies nature. The snow looks like it’s on fire. But in some ways it doesn’t look like a snowball at all. Rather, we see the Earth, with all its greenery crystalised and caked with the cold white powder – or maybe we see the sun. If only we all saw the world like Yayoi Kusama.
