Remo Lienhard, professionally known as Wes21 (or Wes 21), is a Swiss graffiti artist. His artistic endeavours started in 2001 when he began to take an interest in painting. Several years later in 2009, Wes21 attended design school, ultimately becoming a graphic designer. This led Wes21 to become a freelance illustrator/designer, engaging in such projects as large scale murals, canvases, and 3D sculptures to add an unpredictable side to what’s typically expected of graffiti artists.
In 2022, he designed the Swiss Timemachine 25 Francs coin - the first gold coin in that denomination released by Switzerland.
