The oil on canvas 'A Lacemaker, with a Boy Blowing Bubbles' (De Kantwerkster / Kantklossende Vrouw en Bellenblazende Jongen) was painted in 1742 by the Dutch eighteenth century master, Louis de Moni (1698-1771). It is now part of the Mauritshuis collection in The Hague, and on long-term loan to the Museum De Lakenhal, Leiden, the town where De Moni eventually settled and spent the rest of his life.
