Studienblatt_ Bildnis der Comtesse G., und eine Wiederholung ihrer Mundpartie 

This pencil drawing by Wilhelm Trübner, a prominent German artist, features a study of Countess G. The drawing, likely a preparatory work, focuses on the countess's portrait, with an additional sketch of her mouth. It exemplifies Trübner's skill in capturing the likeness of his subjects through loose yet expressive lines. This type of study, common in academic art practice, showcases the artist's working process and provides insight into his approach to portraiture. The drawing is housed in the Städel Museum, a renowned art institution in Frankfurt, Germany.
