A cast of the king's skull was taken at the beginning of the 1900s and has been used by the two men to create a vivid likeness of the ruler's face using the terracotta technique. The technique is used in many Western countries to recreate the faces of unidentified deceased persons and then shown publicly in the hopes of someone recognising the face.

Along with the king, who is also known as Svend II, the terracotta treatment was also applied Queen Sofie, who ruled in the 12th century. Both monarchs are interred at Roskilde Cathedral. The creations are planned to be put on display at the National Museum in the near future.
