Middle Grade Gallery 6

This week in the Middle Grade Gallery, one of a fictional series of four miniatures, as it might have been drawn by Albrecht Dürer. The drawing is first copied, then stolen (and later, recovered) from the Metropolitan Museum of Art in this middle grade novel, one of my favorites of 2009.

The drawing was a tiny framed miniature of a gowned woman kneeling, with her arms around an animal. A lion. She had waves of hair that cascaded down her back, and the lion's mane flowed in similar waves over its massive shoulders.

The drawing above obviously isn't a lion; it's Dürer's Stag Beetle, 1505 (Getty), and it's also a big hint.  Have you figured it out yet?
