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