The sculptures are first created in clay, then covered with a mould that captures the smallest details of their texture. These moulds are sent to various art foundries that use the lost wax technique, the Bocquel  foundry in France and the Art casting foundry in Belgium are world renowned. The bronzes produced are originals signed and numbered from 1/8 to 8/8 and 4 artists’ proofs with the mention E.A. from I/IV to IV/IV. The foundry stamp indicates the provenance and a certificate of authenticity accompanies each work. The patinas, always validated by the artist, may vary from one copy to another, but it is possible to adapt them on request.
