Last Supper

* The relative location of dealers, antique shops, art galleries, and collectors leads us to the places where they were based or had one of their main headquarters. However, this does not always indicate that every artwork that passed through their hands was physically located there. In the case of antique dealers and art merchants, their business often extended across multiple territories; sometimes they would purchase items at their origin and send them directly to clients. Similarly, some collectors owned multiple residences, sometimes in different countries, where they housed their collections. It is often difficult to determine exactly where a specific piece was kept during its time in their possession. Consequently, the main location of the dealer or collector is indicated. These factors should be considered when interpreting the map. Refer to the object's history in each case.
