Provenance Research

Provenance is more than a list of previous owners. It forms a full cultural biography of the object, encompassing its original archaeological setting, circulation history, exhibitions, scholarly publications, and all prior transactions or expert assessments.

This multidisciplinary investigation draws on museum, commercial, and international archives, enriched by iconographic and technical analysis drawn from Guillaume Bresso’s experimental practice.

The legal framework governing cultural goods has grown significantly stricter. The full implementation of Regulation (EU) 2019/880 since June 2025 has introduced enhanced due diligence requirements for importers.

Market studies consistently show that strong provenance significantly increases an object’s value:

Provenance research by Guillaume Bresso enables you to:

• Substantially increase the economic, historical, and cultural value of the work;
• Strengthen its insurability with a credible, accredited valuation;
• Facilitate sales, donations, or estate transfers in full legal compliance;
• Anticipate and reduce future risks;
• Position the collection within an ethical and responsible framework.
