Anthony van Dyck - Zelfportret.jpg
Petrus Christus (ca. 1415‒1472/73) Portrait of a Man with a Falcon, ca. 1445‒50 - The facial features of the “man with a falcon” have been rendered with great care; the fine silverpoint lines blend to create a vibrant surface. The concentration on the face can be interpreted as evidence that the drawing served to capture the subject’s physiognomy for a painted portrait.
