This catalogue includes 551 images: graphics from the collection of the Ciechanowiecki Foundation. The Ciechanowiecki Foundation, founded in 1986, now consists of some 3000 items including paintings, drawings, furniture, silverware, textiles, miniatures, medals and jewels and is the greatest gift that the Royal Castle in Warsaw has ever received. A significant part of the Foundation's collections is part of a permanent exhibition in the interiors of the Royal Castle in Warsaw. The Foundation's collections, in the form of long-term deposits, are used by numerous Polish and foreign museums, thus complementing their own exhibitions. The catalogue of graphic portraits from the collections of the Royal Castle in Warsaw is the first such extensive presentation of the collection. It contains new findings and organizes the current state of research.
