Detail View of Catherine Howard

Detail of Catherine Howard, a miniature attributed to Hans Holbein the Younger. c. 1540-1. Vellum mounted on playing card, diameter 5,1 cm, Royal Collection, Windsor.

The book I took this from calls her Catherine Howard, as do other sources, including Roy Strong in ATC. There are some sources that disagree and call the image Portrait of an Unknown Lady.
