Portret Leona Sapiehy

Executed in a realistic style, the portrait showcases Oleszkiewicz's attention to detail, particularly in the subject's facial features and clothing. The use of oil paint allows for a nuanced representation of textures and colors, contributing to the overall lifelike quality of the work.

Józef Oleszkiewicz, known for his portraits and unconventional behavior, was active in both Vilnius and Saint Petersburg during the reign of Tsar Alexander I, a period that saw a flourishing of portraiture in the Russian Empire. The painting has been preserved and is now held in the National Museum in Kraków.
