[1] With El Equipo Crónica (“Chronicle Team”), formed by the artists Manolo Valdés and Rafael Solbes, Úrculo is considered one of the drivers of pop art in Spain.

His interest in drawing began here after Úrculo discovered the art of Henri de Toulouse-Lautrec, Vincent van Gogh.

In 1967, in Stockholm, he first encountered the American pop art of Andy Warhol, Roy Lichtenstein, and Robert Rauschenberg which he described as "un flechazo" ("love at first sight").

Culis monumentalibus (2001), a provocative and massive sculpture measuring 4 m (13 ft) in height, is located in Oviedo's square, and caused great controversy when it was installed.

[1][4] Úrculo's first bronze sculpture was created in 1984, and others soon followed, such as Homenaje a Santiago Roldán ("Tribute to James Roldan", 1993, Barcelona's Olympic Village), El regreso de Williams B. Arrensberg ("The return of Williams B. Arrensberg", 1993, Oviedo), and Exaltación de la manzana ("Exaltation of the apple", 1996, Villaviciosa).

Perhaps his best-known bronze sculpture is El Viajero (Local Asturian dialect for "The Traveller") - the same (1993) piece described earlier by its formal name, "The Return of Williams B. Arrensberg".

His last individual exhibitions were held at the Fundación Marcelino Botin of Santander and in the gallery Teresa Square, in Valladolid (2000).

In addition to Spain, his works were displayed at expositions, collections and biennials in Germany, France, Cuba, Iran, and the United States.
