Antoni Kozakiewicz's Boy with a Saber (1868) portrays a young boy playing with a large saber. Dressed in historical costume, the boy is fully engaged in imitating military models from his era. The indoor setting suggests a noble or upper-class environment with expensive fabrics and ornate patterns.

The painting mixes realism with a touch of playfulness and humor, as the boy's serious expression contrasts with the oversized saber he is attempting to handle. The woman in the background, watching from behind the curtain with a smile, adds a sense of warmth and affection to the painting.

The work demonstrates Kozakiewicz's ability to portray both the fine details of the environment and the human emotion in a seemingly simple moment.
