FAQ: Authentication and Provenance

Lance Calder, 2025

 1. What is art authentication?

Art authentication is the process of verifying the legitimacy of an artwork, confirming that it was indeed created by the artist to whom it is attributed. This involves expert analysis and documentation. Where possible details of the work and its authenticity should be verified with the artist’s estate or studio. In some circumstances there are published records of an artist’s work, these are called catalogue raisonees. They usually are illustrated and have cataloguing details of works the artist has created, they are a highly useful tool for authentication.


2. Why is provenance important?

Provenance refers to the history of ownership of an artwork. It provides a documented history that can prove the authenticity and value of a piece. Provenance can also reveal an artwork's historical significance, its ownership history and past exhibitions or sales.


3. How does Calder Contemporary ensure the authenticity of artworks?

8. How does Calder Contemporary handle artworks with incomplete provenance?

In cases where provenance is incomplete, we disclose all available information and work with experts to provide as much context as possible. We prioritize transparency and integrity in all our sales. It is fairly common that older works have broken provenance, this does not mean it can’t be authenticated, it just reuquires a little more work. Usually if a work can be traced back to a reputable sale or auction house, this makes the process a little easier.
