Probably Frans Hals (1581-1666) or his workshop, Portrait of a Young Woman, c.The 1660s, Oil on canvas, 60 x 55.5 cm, Ferens Art Gallery, Hull City Museums and Art Galleries, on loan to the National Gallery, London

Formerly attributed to Aelbert Cuyp, this intimate portrait has been recognized since the 1950s as deriving from Frans Hals’s Haarlem workshop. Its sitter remains unidentified—her attire hints at gentility, and the dimensions suggest it may have once been paired with a portrait of her husband.
The question of authorship remains unresolved. The painting may belong to Hals’s late period, executed in his seventies, but it could equally be the work of his son Frans Hals the Younger (1618–1669) or another hand from the studio. Such uncertainty reflects the conditions of seventeenth-century practice, when the individuality of the master was balanced against the collective identity of the workshop.
Hals’s painting method, celebrated for its rapid and direct handling, left little room for elaborate underdrawing or step-by-step collaboration. Yet Haarlem’s Guild of St Luke required that a master’s pupils and assistants follow his style, ensuring recognisable coherence in the studio’s output. This regulation fostered the “workshop style” that blurred distinctions between Hals’s own brush and that of his collaborators.
The portrait therefore illuminates the fluidity of authorship in the Dutch Golden Age. While today’s museums and art market insist on sharply defined attributions, seventeenth-century collectors often accepted high-quality workshop paintings as the master’s own.
Nevertheless, the portrait speaks powerfully of Hals’s late aesthetic: simplicity, a captured presence, and subtle gesture giving voice to a sitter who might otherwise remain silent.
