Portrait of Michał Kazimierz Ogiński (1728–1800), hetman of the Duchy of Lithuania

Pitschmann's meticulous technique is evident in the detailed rendering of textures and adornments. A muted brown background focuses attention on the subject, while the interplay of colors (notably the red cape) adds depth. The overall style aligns with late 18th-century European portraiture, emphasizing realism and the sitter's social standing.

Created in 1796 for an unknown patron or possibly the subject himself, the painting's early history is not well-documented. It is now held in the National Museum in Warsaw, suggesting its acquisition as part of the museum's efforts to collect significant Polish historical figures' portraits.

The portrait reflects the cultural and political climate of late 18th-century Lithuania, highlighting the importance of the hetman title within the Duchy's nobility. It also showcases Pitschmann's adaptation of broader European artistic trends to Polish aristocratic portraiture.

While not widely known outside Polish art historical circles, the portrait contributes to the understanding of late 18th-century Polish nobility and the artistic practices of the time. It remains a significant piece in the National Museum in Warsaw's collection for its historical and artistic value.
