Helge Christoffersen was an extremely skilled craftsman. It took him a short time to model a template for a sculpture. He worked as an assistant for Utzon-Frank, Mogens Bøggild, J.F Willumsen, and Jais Nielsen. In 1947 he was employed at Royal Copenhagen as an assistant to Jais Nielsen. His main work is three reliefs in oxblood glaze, which is hanging in a prominent place in the Danish Parliament at Christiansborg Castle.
In 1948 he received the academy's small gold medal for a large allegorical sculpture "summer", which, together with other seasonal sculptures, was to be erected at the Charlottenborg in Copenhagen.
At the Royal Copenhagen he produced at least 300 unique sculptures and other ceramic objects. Only 14 of them made it into the stoneware catalog – and most of the 14 were only produced in very small quantities. These are great rarities which are highly sought after today. Many of his sculptures have been expensive to produce, and this has set a limit to how much Royal Copenhagen has put on the market. When you look at his unique works today, there is little doubt that they are some of the most imaginative and expressive sculptures from the time.
Helge Christoffersen left Royal Copenhagen in 1954 and established his own studio. He also worked for a number of other studios, and his works for them now appear here and there.
Helge Christoffersen has for instance worked freelance for Just Andersen, and for Hjorts Fabrikker on Bornholm. Here he has designed at least three figures.:
A woman's face, a mermaid (siren) and a sculpture of two cats fighting. These figures are simplified and therefore better suited to produce in larger numbers. The figures were very popular and although there are many of them, almost none are put up for sale. This is of course an expression of the fact that his sculptures also had broad popular appeal.
