I just bought a sculpture that looks like a Bertoia. Can you tell me if it is an original Harry Bertoia?
If you send photos, dimensions and anything else you know about it, we will be happy to take a quick look at no charge. We no longer issue Certificates of Authenticity but you can submit your piece to the Catalogue Raisonné.
How can I get my Bertoia art authenticated, what does it cost, and what will I get?
A: We no longer issue authentications, but you can submit to the Catalogue Raisonné and, if approved, get a CR number. Entries require the art data form, the release form, photos, and payment. 3D object administration fee is $500, and 2D fee is $250. See all details under the catalogue raisonné category at https://harrybertoia.org/catalogue-raisonne/
I’m not sure if I need an appraisal, an authentication, or just a casual opinion? Help!
If you are wondering what your piece might sell for, a casual opinion should suffice. If you are getting art insurance or involved in the 4 D’s (divorce, death, donation, distribution) you will need a full appraisal report. We no longer issue authentications, but you may want to submit to the Catalogue Raisonné (see above).
I have a Bertoia spray. Can I submit it to the Catalogue Raisonné?
The “spray” type sculptures have become problematic in recent years. There are many spray copies and would-be Bertoias out there that are not original Harry Bertoia pieces. If you or your relative/associate acquired it directly from Harry or one of his gallery representatives and you have documentation, the answer is probably yes. If you came by it through second-hand means with no documenting paperwork, it may be a challenge. You can submit to the CR, but it may or may not be approved for entry. We cannot give a CR# to a spray sculpture that does not have substantiating evidence regarding the artist.
I heard that there was an issue of Bertoia sprays for Knoll; is that correct?
While Bertoia did occasionally sell his sprays through Knoll dealers in the 1960s, he never made a specific Knoll series. Each spray was unique. The Knoll managers had such love and respect for Harry that they sold his sculptures with no fee attached, having folks make checks directly to Harry Bertoia.
How can I tell if my Diamond chair or Side chair is an authentic Bertoia by Knoll?
See our extensive how-to article at ID Bertoia Chairs. A book on the Bertoia chairs is in the works.
