The sheet contains a graphic sketch representing a fragmentary image of a woman's face. The work is done in pencil on paper, in a frontal view, encompassing the area below the eyebrow line to part of the neck. This cropped composition highlights the nature of the sketch-observation, which aims to study individual morphological details. The model is depicted with her mouth slightly open, with the front incisors particularly clearly drawn, which gives the image expressiveness and naturalism. This detail indicates the artist's interest in capturing the instantaneous state of facial expression, rather than just a static portrait image. One of the ears has a mark that is probably a piece of jewellery, but its interpretation is left schematic. This may indicate either the incompleteness of the work or the secondary nature of this motif in comparison with the main focus on the anatomy of the face. Hatching is used sparingly, concentrated in areas such as the eyes, lips, chin, and neck, while other areas are left with minimal detail. This technique creates a sense of lightness and, simultaneously, captures the plasticity of the features. The overall composition lacks background or contextual elements, which is typical of educational or research drawings. The stylistic features of the work allow it to be interpreted as an auxiliary sketch based on a photographic source. It reveals the author's interest in studying the details of facial expressions and the specifics of individual facial plasticity. The incompleteness of the composition and the absence of additional elements can be seen as evidence of the procedural nature of the drawing, in which the primary task was to identify and analyse the specific features of the model. Thus, the image is a valuable example of the artist's research practice in the field of portraiture.
