Lunia Czechowska and her husband knew Modigliani through his dealer, Léopold Zborowski, who by around 1917 had become the artist's primary dealer, letting him use his apartment as a studio and organising his shows^[1]. That circle, close-knit and largely Polish or Eastern European in its core, gave Modigliani a small pool of sitters he could return to repeatedly rather than relying on models found through cafés or introductions. Zborowski's own household, his wife Anna among them, sat for Modigliani more than once, and Czechowska belongs to that same inner group: friends of the dealer who became, in effect, friends and regular sitters of the artist himself. The portrait dates to around 1917, the same year Modigliani's dealership with Zborowski solidified and the year he met Jeanne Hébuterne, marking a period when his mature style, and his most productive years as a painter, were taking shape.

Most of Modigliani's sitters appear once. A small number appear many times, and Czechowska is among them, with several surviving paintings of her from this period. The clearest comparison is Jeanne Hébuterne, who was painted in more than twenty surviving portraits between 1917 and 1920, none of them dated by the artist himself, and whose exact sequence remains disputed by cataloguers to this day^[2]. Czechowska's position as a repeat sitter, second in frequency only to Hébuterne among named individuals, places her in unusually close company. Painting a sitter many times allowed Modigliani to vary pose and mood while keeping his underlying vocabulary, the elongated neck, the flattened oval face, the blank eyes, constant. It also suggests a sitter patient enough, and close enough to the artist's circle, to submit to his working method more than once.

Czechowska outlived Modigliani by decades, and she later gave her own recollections of the artist to one of his earliest biographers, material that fed into a catalogue of his work published in 1958. Firsthand testimony of this kind is rare in Modigliani's case: the artist died young, left few letters of substance, and much of what is known about his working habits and personality comes second-hand through friends, dealers and fellow painters rather than his own words. A sitter who knew him well enough to pose repeatedly, and who was still alive and willing to speak decades after his death, is accordingly a disproportionately important source for later scholarship on the artist, even where her testimony cannot always be checked against independent documentation.
