Portrait of a boy, half-length, in a violet embroidered coat with a lace collar; and Portrait of a girl, half-length, in a black dress with gold embroidered white sleeves and a lace headdress, holding a rose

We are grateful to Mrs Hanako Kawanchi of the University of Osaka for pointing out similarities with the Wintzler family portrait by Gotthardt de Wedig in the Wallraf-Richartz-Museum, Cologne. She believes the artist must have been familiar with the oeuvre of Gortzius Geldorp, and was influenced by portrait painters from Cologne of a generation later.
