Jaroslava, Mucha's first child, was born in 1909 in New York, during the family's stay in America. She appears in numerous pictures and designs, including Czechoslovak banknotes.
In this half-length frontal portrait, Jaroslava sits in an elaborate white headscarf with her chin in her hands.
When Mucha was working on the Slav Epic at Zbiroh, Western Bohemia, Jaroslava not only posed for the paintings, but also worked as her father's technical assistant. This early training may have helped her pursue her career as a conservator of fine art.
