The sources of original vintage photos of Slovenian gymnasts used for decoration of Munda house are:
- National library - Narodna in Univerzitetna knjižnica NUK – according to many the most beautiful building in Ljubljana just 2 min from here
- Historical Archives Ljubljana - Zgodovinski arhiv Ljubljana
- The Archives of Republic Slovenia - Arhiv Republike Slovenije
- Sports Museum - Športni muzej
- National Museum of Contemporary History - Muzej novejše zgodovine
- Personal collection of Mr. Janez Šlibar (above pommel horse).
Vintage photos of slovenian gymnastics were really very difficult to obtain.
