You are encouraged to either email or call for an initial consultation. Andy Warhol paintings, prints, sculpture, Polaroids, and drawings will be considered. Memorabilia, such as an actual Campbell's Soup Can that's been signed by Warhol, items of clothing screened with a Warhol image, etcetera, are not evaluated by this service. The same holds true for Basquiat, Haring, and Pollock: paintings, sculpture, and drawings will be considered.

You may pay securely with a credit card via PayPal by clicking the button just below. Please be sure to check the box "No Shipping Required." Your payment is non-refundable.

Step 3: Upload image files

The final step is to email high quality digital images of the front and back of the work of art, including close-ups of any labels or signature. In addition, we want to know about the provenance (history) of the work of art, specifically the chronological "food chain" of everyone who has ever owned or exhibited it. Also of interest is support material, which can include any written documentation such as an invoice, a letter from a previous owner stating how he acquired it, an exhibition catalog in which it is reproduced, etc.

Because the file uploader is limited by the number and total file size of uploads at one time, you may need to send this form several times to attach all of your images.

What You Receive

Upon completion of our research you will initially receive notification by email, followed by a hard copy, stating whether your work of art was found to be inauthentic or authentic. The letter will contain a detailed explanation of how we came to this conclusion. Each work of art that we inspect, whether found to be genuine or not, will be documented and assigned a number that's recorded in our archives. Turnaround time is seven to ten days.
