How Do I Locate Image Associated With a Copyright Registration?

Dear Rich: If I'm provided with a registration number for a visual art's copyright, how can I check its image? I have tried searching on www.copyright.gov, but the result doesn't include the image.

The Copyright Office Public Records Portal does not provide copies of the images, books, movies, or other copyrighted materials registered under copyright law. These works are considered deposit materials (because the registrant deposits copies with the Copyright Office), and you must request them from the Research and Certification Section. (Keep in mind that the Copyright Office does not retain all deposited works for copyright registration.) The Copyright Office will only provide deposit materials in three situations: (1) you are the copyright owner (and can prove it), (2) you are preparing for litigation, and you complete the Copyright Office Litigation Statement Form, or (3) A court order is issued for the deposited material. All of this information (and more) is provided in Copyright Circular 6.
