COULD YOUR PAINTING BE BY GUNNAR S. GUNDERSEN?

Previously unknown works by important artists continue to emerge from private collections, estates, inheritances, and long-held family possessions. While authentic works by Gunnar S. Gundersen may be rare, every work deserves to be evaluated on its own merits rather than dismissed simply because it is unfamiliar or undocumented.

If you believe your painting may be by Gunnar S. Gundersen, obtaining an independent professional opinion is the appropriate first step.

We have specialized in the authentication of works attributed to Gunnar S. Gundersen since 2002. We issue Certificates of Authenticity (COAs), Authentication Reports, appraisals, valuations, provenance reports, and provide buying, selling, brokerage, and investment advisory services for collectors, attorneys, insurers, financial institutions, estates, museums, and private clients worldwide.

Getting started is straightforward. Simply send us photographs of the work together with its dimensions and any information you have regarding its history or ownership. After reviewing the material, we will recommend the most appropriate course of action.

AUTHENTICATION

Is this a Gunnar S. Gundersen?

From a single photograph of ordinary quality, we can often determine whether a painting appears consistent with Gundersen’s work or whether it clearly does not. His abstract compositions require careful consideration of color relationships, geometric forms, spatial effects, materials, and execution.

What services do you provide?

We provide authentication, certification, Certificates of Authenticity (COAs), Authentication Reports, appraisals and valuations, provenance research, private sales and brokerage, investment advice, and analytical art market research.

Is it possible to discover a previously unknown Gunnar S. Gundersen today?

Yes. Paintings and graphic works can remain in private collections and family estates for decades without being widely published or documented. Gundersen worked predominantly in easel painting but also made a significant contribution to graphic and monumental art.

Do I need to get my Gunnar S. Gundersen authenticated?

Yes. Authentication is essential if you wish to sell your work for its full market value. It is also important for insurance, estate planning, charitable donations, financing, and many legal purposes.

Is it complicated to get a Gunnar S. Gundersen authenticated?

Not for you. Simply send us photographs of the front and reverse, close-up photographs of important details and any signatures or inscriptions, the dimensions, and anything you know about the work’s history. The investigation itself is our responsibility.

How long does it take to authenticate a Gunnar S. Gundersen?

It depends on how much is already known about the work when we begin the investigation. In the simplest cases, authenticity can be confirmed within a couple of weeks. More complex cases may require several months.

How much does it cost to authenticate a Gunnar S. Gundersen?

From the low hundreds to the high thousands. It depends on how much is already known and documented, where relevant archives are located, and whether travel or scientific testing is required.

Can a signature alone prove that a Gunnar S. Gundersen painting is authentic?

No. A signature must be considered together with the painting’s composition, technique, color relationships, materials, support, surface, date, and provenance. A signature alone is never sufficient proof of authorship.

Can an unsigned Gunnar S. Gundersen painting still be authentic?

Yes. The absence of a signature does not by itself exclude a painting from consideration. The work should be assessed using the complete stylistic, technical, material, and documentary evidence.

What documents help authenticate a Gunnar S. Gundersen painting?

Any document that mentions, describes, illustrates, or refers to the painting may assist the authentication. Photographs, invoices, correspondence, exhibition records, conservation reports, insurance documents, auction records, and family papers can all contribute valuable evidence.

Can a Gunnar S. Gundersen painting be authenticated from photographs?

Yes. High-quality photography is an extremely useful authentication tool and allows us to study composition, color, paint surface, support, signatures, inscriptions, and condition remotely. When additional evidence is required, we may recommend an in-person examination. We examine works worldwide.

Is it always necessary to perform scientific analyses of a Gunnar S. Gundersen?

No. Many works can be authenticated through research, provenance investigation, comparative analysis, and technical examination. Scientific testing is generally reserved for more difficult cases when questions remain concerning the age or composition of pigments, binders, grounds, canvas, or other materials.

What if my Gunnar S. Gundersen has no provenance?

Incomplete provenance is common. When provenance is incomplete, authentication relies more heavily on comparative research, technical examination, photography, material evidence, and, where appropriate, scientific testing.

Yes. Upon completion of the authentication, we issue a Certificate of Authenticity (COA) together with a detailed and fully referenced Authentication Report.
