Steinar Caspari (b. 1983) is considered one of Norway's foremost graffiti artists, with a world-class technical skill level. He is self-taught, and through over 20 years in graffiti and street art, he has developed a unique style that has made him a sought-after artist both nationally and internationally.

Caspari began his artistic journey in the late 1990s. Early on, he discovered that it wasn't the adrenaline of illegal graffiti that drove him, but the desire to master the craft and develop a distinctive artistic voice. In 2005, he was behind one of the country's first commercial graffiti exhibitions in Larvik, where all the works were sold within 30 hours – an event that marked the beginning of a professional career.
