2012, Edwin Bormann has worked as a freelance artist and workshop leader for school classes and companies. In public spaces, he works primarily on motifs and is known for his large-scale portraits that he and his team from the 0815 studio in Paderborn have left behind. For his work on Asseburgstraße, the graffiti artist chose a portrait of the series character Sheldon Cooper (The Big Bang Theory). Bormann decided to create a portrait of the series hero in a Superman shirt. A special feature of Edwin Bormann's murals is that he often works with coffee paints. He used his ecological coffee paints for some parts in the face of Sheldon Cooper's portrait.
