The Collection of Realia preserves the personal items of the donor Pavle Beljanski, of his family members and artists from the collection (painting kits and objects from their studios). The most valuable items in the Collection are personal items of Pavle Beljanski and a ceremonial diplomatic suit, donated to the museum after his death in 1965. This copy belongs to the 2nd Class suits designed according to the Regulations on Tailoring and Wearing Diplomatic-Consular Uniforms from 1937, intended for secretaries and consuls general assigned in foreign countries at the Ministry of Foreign Affairs of the Kingdom of Yugoslavia. The protocol uniform from The Memorial Collection was made in the Italian workshop of Enrico Cucci in Rome, the famous supplier of His Royal Highness the Prince of Piedmont – Crown Prince of Umberto, as written on the lining of the bicorne.
