Dolk is a Norwegian street/urban artist who made his mark in the art world with whimsical and fun stencil and spray paint and then, suddenly, reinvented his style and started making scratch art. Like literally taking a key and scratching metal. A little to avate guard for me. But I love some of his early work like this piece, Teddy Riot, Kitty Riot, and some of his monkey-themed work. His early stuff is still very collectible and sought after.
