HOW THE BLANCHE RECORD SHOULD BE CORRECTED
Why the 1920–1930 Date Fails

The 1920–1930 date range attributed to this bust fails on three independent grounds. Each ground is sufficient on its own to require the date to be flagged as contested. Together they make the late dating structurally indefensible.
The first ground is the artist’s death. Rembrandt Bugatti died on 8 January 1916 in Paris. He was thirty-one years old. Any date range beginning in 1920 therefore cannot represent a work produced during his lifetime under normal portrait commission circumstances. The 1920–1930 frame, if it refers to a direct portrait sitting, describes something that was physically impossible.
The second ground is the sitter’s emigration. Blanche Denise Ferrero-Willmann migrated to the United States in 1907. No evidence of a return to Paris during the 1920s or 1930s exists in the accessible record. For a Paris portrait sitting to have taken place in that decade, she would have needed to return. The absence of evidence places the burden of proof on anyone who wishes to maintain the late date: they must account for where and when the sitting took place.
The third ground is the origin of the date itself. The 1920–1930 range does not appear to derive from case-specific research. It has the character of a class convention: a broad date range applied to a category of Bugatti bronzes to reflect general market uncertainty about posthumous casts and later foundry editions. Applied to a specific identified portrait with a named sitter, such a convention cannot stand without case-specific verification. That verification was never performed.
