The subject of the current formal restitution claim are seven paintings by Italian artists that are currently held at the Pushkin State Museum of Fine Arts in Moscow. They were produced between the 14th and 18th centuries by artists such as Spinello Aretino and Lorenzo di Credi.
The works were looted by the Red Army, a faction of Russian forces, during the World War II. Prior to their seizures, some were held in the collections of the Czartoryski family in Gołuchów, at the Wilanów Palace, and in Poznań, Wrocław and Łódź.
