Das gelbe Monster (The yellow monster)

This artwork is by Spe_Kunst (also known as Spe), whose work is a common sight in the Hamburg cityscape. The artist himself often refers to this iconic figure as "Das gelbe Monster" (or "El monstruo amarillo" in Spanish): the cartoon-like, yellow monster has pointed ears (or small horns), squinting eyes, and a massive, wide-open mouth filled with sharp teeth. Despite its wild appearance, the works often convey humorous or peaceful messages.

The artist frequently collaborates with other prominent figures in the street art scene, often incorporating his signature yellow characters into sticker exchanges or joint street art projects.
