16th-CENTURY FRENCH OR GERMAN SCHOOL Double-sided sketch: Artist at His Workbench / Portrait of a Man Wearing a Hat Pen and Indian ink, with highlights of white gouache and gold on gray-primed paper. Annotated: “C” at the top and numbered “4” and “3” on the reverse. Unidentified stamp in the lower right corner. (Surface wear, small tear in the upper right corner, sun-faded). 16.3 x 23.5 cm Provenance: Bayeux Enchères auction, Hôtel Drouot, Paris, July 13, 2020, lot 8. Several drawings by the same artist have been published as works from the studio of Jacob Weyer (1623–1670) (see: Timo Trümper, *Der Hamburger Maler und Zeichner Jacob Weyer (1623–1670)*, nos. ZD 31-32-33). Clearly, this series is the work of an artist from an earlier period, either French or German.
