In Portrait of a Boy with a White Shirt and Brown Leather Belt, we see a young boy dressed in a crisp white shirt, complemented by a brown leather belt. The boy's expression is calm and introspective, drawing the viewer's attention. The background is softly blurred, emphasizing the figure in the foreground.

The color palette is warm, with soft browns and whites creating a harmonious effect. The painting is executed in oil on canvas, a common medium for portraits during the 19th century. The artist's brushwork is meticulous, capturing the texture of the boy's shirt and the smoothness of the leather belt. Light plays a significant role in the composition, highlighting the boy's face and creating depth.

The overall composition adheres to the principles of realism, focusing on accurate representation. Raimundo de Madrazo y Garreta was a prominent Spanish painter known for his portraits and historical scenes. This work reflects his skill in capturing the essence of youth and innocence. An interesting fact about this painting is that it showcases the artist's ability to blend realism with a touch of idealism, making the boy appear both relatable and slightly idealized.

It is a fine example of 19th-century portraiture in Spain.
