What is Art Authentication?

An art authentication is a certificate issued by the sole recognized authenticator for an artist. This expert certifies whether a painting is authentic or not. They are acknowledged by major auction houses worldwide.

Typically, this expert has a personal connection to the artist. For instance, Claude Picasso is the recognized expert for his grandfather, Pablo Picasso. Similarly, Julius Held was the unanimously recognized expert for Peter Paul Rubens' artworks. Today, this privilege belongs to the Rubenianum in Antwerp, Belgium.

The Challenges of Authenticating Old Master Paintings

Authenticating the authorship of an old master painting is extremely challenging, especially for renowned artists like Rembrandt and Raphael. The process requires the approval of several important experts, making it time-consuming and difficult to obtain. If someone wishes to authenticate a Raphael painting today, it can take a minimum of five years and be quite costly.

What Do Authentication Experts Require?

Authentication experts typically request the following:

A. Photos

Black and White Photos: Three black and white photos, sized 5 x 6 inches or similar.
Color Photos: Three color photos, also sized 5 x 6 inches or similar.
Digital Images: Although an Ektachrome transparency was once requested, experts now prefer very large digital photos of the artwork on a USB drive. It’s essential that these photos are taken by a professional photographer.

B. Documents

Provenance Explanation: A complete explanation of the painting's provenance is necessary. This document outlines how the owner came into possession of the artwork and must be verifiable. Simply stating that you received the painting from Picasso himself on New Year's Eve 1957 is insufficient. You need supporting documents, such as photos.
Condition Report: This report should detail any restoration work done on the artwork and its current state of conservation.
Back Photos: Include photos of the back of the artwork and detailed images of all annotations made to the canvas or frame. This includes photos of restoration patches.
Bill of Sale: If available, include a bill of sale from a gallery or individual from whom the artwork was purchased.

The Importance of Expert Assistance

It is strongly advised to seek help from an expert for two main reasons:

File Creation: An experienced expert can create the comprehensive file described above.
Representation: They can represent you to the authenticator. An expert will prepare a file that includes, but is not limited to:
Justification of authenticity through comparisons with other works by the artist.
Comparisons with other works by the same artist from the same period.
Reestablishment of the work in the "catalogue raisonné."
Research on the historical context and provenance.
Analysis of the painting's history.
Graphology analysis of handwriting.
Signature analysis.
On-site analysis of the painting.
Study of the pigments and support.
Examination of the painting's style.
Wood lamp tests.
Comparisons with other artists from the same period.

Navigating the French Authentication Process

When dealing with French artists and French authenticators, it is particularly important to have representation. In France, an authenticator has the authority to seize a painting they believe to be a copy or a fake, and they can have it destroyed under legal supervision. However, they cannot seize the artwork if the owner is not present at the meeting.

Conclusion

The process of art authentication is intricate and requires careful attention to detail. Whether you are an owner seeking to authenticate a piece or simply interested in the process, understanding the requirements and challenges can help you navigate this complex field.
