Brian Donnelly was born in 1974 and is known professionally as Kaws (stylized as KAWS). He is one of the most successful living contemporary American artists and also a designer. His work includes repeated use of a cast of figurative characters and motifs, some dating back to the beginning of his career in the 1990s, initially painted in 2D and later realised in 3D. Some of his characters are his own creations while others are reworked versions of existing icons. Kaws' sculptures range in size from a few inches to ten metres tall and are made from various materials including fibreglass, aluminium, wood, bronze and a steel pontoon inflatable raft.
