Unknown artist - Study after Enrico Gamba " On the terrace"

Elegant antique drawing executed entirely by hand in chalk and pastel on paper, dating from the late 19th century (circa 1875-1890). This artwork is a high-quality academic studio study (d'après) based on the famous painting "Sulla terrazza" (On the Terrace) by the renowned Italian master Enrico Gamba (1831–1883).
As is typical for studio bozzetti or academic exercises of the period (such as those from the Albertina Academy), the work is unsigned, focusing purely on technical mastery.
