On the obverse side of the work are five portraits executed in a graphic technique that pays attention to light and shadow modelling and the constructive construction of forms characteristic of the academic school. The main ones are four images of bearded men of different ages in suits, two of which are presented in a waistline format. These two figures are placed within the interior: both are seated in armchairs, which adds to the chamber-like character of the compositions. One of the men is holding a book, which creates an intellectual context. Both portraits are executed in a restrained manner, characterised by laconic lines, moderate shading, attention to the expressiveness of the gesture, and the positioning of the hands. The shoulder-length portraits of the other two men are characterised by psychologism: concentrated gazes, wrinkled foreheads, and different types of beards. Both images are sketchy in their execution, but they are obviously based on the works of other authors of the time (this is indicated by the specific cut of the clothes and styles). The fifth portrait, of an elderly woman, is presented in a close-up, almost profile view. The face is presented with a subtle psychologism: deep-set eyes, restrained gaze, closed lips. The clothes give the figure a sense of austerity and balance. This image, unlike the male portraits, is more observational in nature. On the back of the sheet are studies of nude female models. Three female figures are depicted in different positions: two are sitting (one leaning on an amphora (?) with her hand), the third is standing with her back and her hands on her knees. All the figures are captured with attention to anatomy, the plasticity of soft forms, and the balance of body weight and natural limb positions. The compositions are static, aimed at capturing the natural state, but the way the body is represented, especially in the standing figure, shows an attempt to convey a living model. These drawings, as well as others in the series, exemplify systematic studio work from life, where accuracy, observation, variation of angles, and expressive shading demonstrate the artist's deep understanding of the principles of academic drawing.
