Olovson worked almost exclusively in bronze, relying on the traditional lost‑wax process and a small circle of trusted founders in France and Sweden. He remained closely involved at each key stage, from mould to patina, to ensure that every cast stayed faithful to his original modelling.

His sculptures were produced in carefully controlled editions, often realised over many years with the same foundries. This disciplined approach to casting underpins the consistency, clarity and enduring presence that distinguish his bronzes.

The remaining Gudmar Olovson bronzes are being cast in a tightly controlled, estate‑led process that honours both the artist’s intentions and French legal standards for posthumous editions. Working from original plasters and authorised models, his heirs oversee the completion of only those editions that were started in his lifetime, maintaining the same lost‑wax techniques and using the Coubertin Foundry and other founders whom Olovson himself held in the highest esteem.

Each new cast is documented with full edition details and issued with an estate certificate, so future collectors can clearly distinguish lifetime bronzes from estate casts while remaining confident in the continuity of quality and provenance. This estate stewardship ensures that the final works to enter the market do so with complete transparency and at the same exacting standard of craftsmanship that defined Olovson’s original practice.
