What is the purpose of a Hors Commerce proof?

A Hors Commerce proof, often abbreviated as H.C. proof, is specifically used as an exhibition copy. These proofs are typically printed in limited quantities and are designated as not intended for sale. Their main purpose is to serve as an example of an artwork or print for display purposes, such as gallery exhibitions or portfolios. This allows artists to showcase their work without the intention of selling those particular proofs.

While the other responses touch on aspects related to printmaking and editions, they do not accurately capture the unique role of the Hors Commerce proof in the context of art exhibitions and its distinction from commercially available prints.
