The sheet features three separate portrait images created using different graphic techniques. They are not linked by a single compositional concept and probably represent Yulian Zaiats' educational or research sketches based on various sources. On the left is a shoulder-length portrait of an elderly man facing forward, done in ink. The laconic linear manner forms a distinct silhouette, clearly outlining the facial features. The interpretation strives for a generalised image, without extensive modelling of texture and details. In the centre of the sheet is a drawing based on the well-known work by Valentyn Sierov – a portrait of Kleopatra Obninska, "Woman with a Rabbit” (1904; original – cardboard, charcoal, pastel, sanguine). In Yulian Zaiats' version, the model is presented in a more linear and rigid manner, with an emphasis on the structure of the face and silhouette. In contrast, the original features a younger female image that is interpreted more softly, utilising rich tonal transitions. In Y. Zaiats' drawing, there is a noticeable tendency towards academic analysis of form, which distinguishes it from the emotionally and plastically expressive original. On the right is a sketch from a portrait by Valentyn Sierov of his colleague, the etcher Vasylii Mate (original: etching, 1889; third or fourth version). The drawing reproduces the main features of the composition and the character of the model, but the interpretation is simplified, with the background and secondary elements practically absent. The author focuses primarily on the face and its proportions, which is consistent with the tasks of copying practice. The drawings, executed in various techniques (ink and pencil), testify to the research nature of Yulian Zaiats' work, which aimed to study portrait plasticity, compare his own manner of execution with original stylistic techniques, and seek means to deepen the characterisation of the model.
