There are two versions of this portrait of the composer Jaume Pahissa: this one, in which the head emerges from the marble block in the middle of work, and a second, in bronze, centered on the character's face and which is also preserved in the Museum.

With the first, he participated in several official art exhibitions, of which the Barcelona Art Exhibition of 1918 should be highlighted, which marked the artistic presentation of Marès in the city, and with which he obtained a prize awarded by the Real Cercle Artístic.

The portrait, worked from the natural, shows the influence of the work of the sculptor Auguste Rodin, fundamentally by the use of the resource of the modeled face that arises from the shapeless marble, popularized by many modernist artists, and by the treatment of the face and hair. However, the work does not at all exude the intense expressiveness of the French sculptor's portraits. Rather, when presenting the character, an idealistic will is evident that distances him from Rodin and his influence.
