Returning back to her native Czech lands, Junková continued to work with her love of cars. In the 1930s, she collaborated with the prestigious Czech company Baťa on tire development. She joined the Czechoslovak Automobile Club for Moravia and Silesia, built a circuit and organized races. She remained an ambassador for Bugatti. After WWII, Junková married sports and motoring journalist Ladislav Khás. However, with the Communist takeover in Czechoslovakia in 1948, Junková was banned from traveling abroad as her lifestyle was deemed “bourgeois.” She became a mostly forgotten icon in the West.
