According to currently accepted dating, Zajec produced this realistic bust called Portrait of a Girl (Portret Deklice) around 1905. In its purchasing records, the Ministry for Education and Worship mentions from April 1913 a statue by France Štukl Zajec called “statue of a young girl”, purchased for 300 krones and donated to the state gallery in Germany. Tomislav Vignjević connected the two details and surmised it must be the patinated plaster Portrait of a Girl, today housed at the National Gallery. After all, the Gallery purchased from the Viennese Staatsgaleria a statue entitled A Girl. Perhaps the dating should be reconsidered and the cast was produced during his Parisian escapades or after his return to Ljubljana (1907–1908), as the hair, the parts around the eyes, and the roughly hewn lower part make this statue comparable to his later female bust called the Woman of Trieste (Portret Tržačanke, NG P 380).
The sculptor was fond of depicting girls. The childlike motif was a common theme in both his sculpted as well as drawn works. This realistic plaster statue portrays a girl with crossed arms, garbed in a plain dress with short sleeves, but with well-kempt hair drawn back into braided buns around her ears. Her face and arms are smoothed, as opposed to the rough texture of the base. The girl’s countenance is confident, though her face betrays a hint of flippancy.
