The background is subtly muted, allowing the figure to stand out prominently. The painting is executed in oil on canvas, a medium that Goya mastered throughout his career. The dimensions are approximately 100 x 130 cm, making it a sizable work that commands attention. Goya's technique is evident in the delicate brushwork and the play of light on the fabric of the clothing.

The details in the face and attire reflect Goya's keen observation and ability to capture personality. Francisco de Goya was a prominent Spanish painter known for his ability to convey emotion and character through portraiture. This particular work, created around 1787, showcases Goya's transition into Romanticism, where he began to emphasize individual expression. An interesting fact about this painting is that it was commissioned by the subject himself, reflecting the importance of portraiture in establishing social status during that era.

Goya's portrayal of Osorio is not just a representation but also a commentary on the nobility of his time.
