I could see the price if it was an original drawing signed by the artist, but not sure for a print or copy. All the best with your sales though.
They are not prints. The artwork is printed onto an aluminum panel that is then treated with a high-gloss protective coating and secured with 1/2" wood spacers. They offer a beautiful shine and a deep reflection. They are also limited to 10 or, in some cases, as the Symbol Phoenix, 5.
