The collection was divided into sections of ethnography (clothes, textile, music instruments), archeology, numismatics and library (mostly, of incunabulas and manuscripts).

At that time, the collection already contained Skaryna's Bible, a Statute of Lithuania, several Slutsk belts, issues of Mużyckaja prauda.

The museum was managed by Ivan's younger brother, Anton Luckievič, and engineer Liavon Dubeikauski.

[5] A subsequent inventory from 1933 shows that the museum expanded to include a prehistoric section of 200 items from Palaeolithic, Neolithic, Bronze and Iron Ages, a sigillographic collection of 103 stamps, collections of rings, religious objects (old crosses, icons, clothes), painting and drawings, wooden sculpture.

The ethnographic section contained textiles, clothes, musical instruments, clay and glass vessels.

The committee finished its work in June 1945, distributing museum's collections between other institutions of Lithuania and Belarus: items with text in the Belarusian language were transferred to Belarus while items connected with the history of the Grand Duchy of Lithuania were given to Lithuanian museums.

The initiative group, including Halina Voitsik, Siaržuk and Liudevika Vituška, Siarhei Dubaviets, Tatiana Poklad, registered NGO Ivan Lutskievitch Belarusian Museum in Lithuania.

It presented works of Belarusian feminine artists Zoia Koush, Zhana Gladko, Sviatlana Petushkova, Aliesia Zhytkuevitch.

[9] During its first year, the revived museum organised exhibitions of paintings, photographs and book graphics, presentations of books by Uladzimir Nyaklyayew, Volha Hapeyeva, Jury Dzikavitski, concerts of Zmitar Bartosik, Zmitar Vajciukievich, Andrej Hadanovich, poetry festivals, workshops, theatre plays.
