We are looking at an educational copy, executed in the ink and pen technique typical of early 20th-century educational drawing. The image reproduces a portrait of a young man created between 1613 and 1615 by the Flemish painter Peter Paul Rubens, one of the leading representatives of the Baroque portrait genre. The copy accurately reproduces the basic structure of the composition, preserving the psychological richness of the image, typical of Rubens. The model is represented in three-quarters, with face turned to the viewer, an expression of slight interest and restrained confidence. The complexity of creating a shape with ink and pen makes the copyist pay extra attention to the modelling of volumes, the distribution of light and shadow, as well as the transfer of textures, including hair, a massive white collar and shadows under the eyes. Here, the softness of the stroke is transformed into a linear and rhythmic structure, forcing the student to rethink the form through the black and white graphic language. In the early twentieth century, making such copies was an important part of art education, especially in the context of academies and studios that sought to develop a deep understanding of plasticity, form, and emotional expression in future artists through close study of the masterpieces of the old masters. Ink and pen as a technique required extraordinary precision and discipline: without the possibility of correction, it fostered confidence in the hand, as well as the ability to work with contrast and laconicism of expressive means. The choice of this particular portrait by Rubens was not accidental: it combines the restrained nobility of the model, characteristic of aristocratic Flemish portraiture, with the exquisite simplicity of the painting. Such images were especially valued in the academic teaching environment, where portraiture served not only as an exercise in composition but also as a way of learning about the psychology of the image. Thus, this drawing can be seen as an example of an academic work with a form in which the author combines an analytical approach to Rubens' masterpiece with the technical discipline of classical graphic writing. On the reverse is a fragment of an unidentified work with a woman and draperies, executed in pencil.
