Museum "Staro selo" Kumrovec is the first and most famous open-air ethnographic museum in Croatia. In addition to the birth house of Josip Broz Tito, the museum consists of about 30 preserved and restored traditional residential and commercial buildings containing exhibitions of crafts and customs of the Zagorje region from the end of the 19th and the beginning of the 20th century.

At the end of the 1940s, the idea arose to incorporate the core of Kumrovec under the heritage protection measures, and for this purpose Gušić wrote a study on this settlement. In 1950, she developed an ethnographic presentation of a part of Tito's house. She also created a catalogue for the preservation of 61 buildings in Kumrovec and Lončari. In 1969, "Staro selo" Kumrovec was registered in the Register of cultural monuments of 1st category.
