The fantasy portrait shows the young character, with his adolescent mustache barely hinted above the upper lip and a long hairstyle, who wears a long tunic with wide sleeves over a shirt closed at the neck by a ribbon forming an elaborate float under the chin. He plays a violin, seated on a sort of chest, on the lower edge of which the author's signature is handwritten: J. Lecurieux Del. et Sculp .. Four instruments hang on his right and on the left some sheets that look like technical drawings are attached to the wall, while a sheet with unrecognizable printed inscriptions is placed near his knees. The five instruments, as well as the bow, are drawn with much approximation.
