AZ Auction

Founded in 2005 by Arnaud de Partz under the name "Banque Dessinée," our auction house initially focused on comic art. This specialization, maintained until 2016, enabled us to quickly become a European leader in this field—often referred to as the "Ninth Art."

In 2017, the firm adopted the name "Millon Belgique" following Alexandre Millon’s acquisition of an equity stake. This period saw the development of new departments—Jewelry & Watches and Paintings & Works of Art—managed from our Brussels premises.

After seven years of partnership, Arnaud de Partz chose to take the helm independently in 2024. The company returned to 100% Belgian ownership and adopted a new name: AZ Auction—a nod to its founder.

Today, our team of experts assists collectors and sellers across all our departments. Based on Avenue des Casernes in Brussels, we organize multiple catalogued and online auctions each year, driven by the same passion that has inspired us for two decades.
