A collection of observational sketches of a rooster, rendered in charcoal and coloured chalk by a young Pablo Picasso.

This sheet of studies captures the young Pablo Picasso observing the anatomy and movement of a rooster. Executed during his formative years in Spain, the work demonstrates his early technical proficiency and his interest in naturalistic observation. The artist employs charcoal to define the structural forms of the birds, while touches of coloured chalk provide subtle tonal variation to the plumage.

Picasso explores the rooster from multiple angles: standing, pecking, and in profile. The composition is informal, reflecting the nature of a sketchbook page where the artist experiments with posture and gesture. The lines are fluid, showing a confidence in draughtsmanship that would define his later career. The paper, with its warm, neutral tone, acts as a mid-tone, allowing the artist to build volume through light and shadow rather than relying on heavy shading.

This piece offers a glimpse into the artist's early training, where he engaged with traditional subjects before moving toward the radical stylistic shifts of his later periods. The signature, 'P. Ruiz', is a reminder of his early practice of using his father's surname before adopting his mother's name, Picasso, as his primary professional identifier. The work is a study in economy of line, where a few strokes suggest the weight and character of the animal. It remains a clear example of the artist's ability to capture the essence of a subject through direct, observational drawing.
