Provenance documentation is crucial for verifying the authenticity and value of a metal sculpture. Here are the most effective ways to ensure accurate record-keeping:

1. Artist Records & Certificates – Obtain signed certificates of authenticity from the artist or foundry, detailing materials, creation date, and edition numbers.

2. Photographic Documentation – Maintain high-resolution images of the sculpture from different angles, including close-ups of signatures or markings.

3. Exhibition & Sale Records – Track exhibition history, auction records, and sales receipts to establish a clear ownership timeline.

4. Material & Process Documentation – Preserve records of metal composition, casting techniques, and restoration work to support conservation efforts.

5. Digital & Blockchain Solutions – Use blockchain-based ledgers or digital registries to create tamper-proof provenance records.

By implementing these methods, collectors and institutions can safeguard the legacy of metal sculptures while enhancing their market credibility.
