Answer:
The artist collective, Los Carpinteros (The Carpenters) of Havana, Cuba, adopted their name to renounce the idea of individual authorship of art in favor of <u>an old guild tradition of artisans and skilled laborers.</u>
Explanation:
Los Carpinteros, or The Carpenters in English, were a Cuban art collective formed by Marco Antonio Castillo Valdes, Dagoberto Rodriguez Sanchez and Alexandre Arrechea. The latter left the collective in 2003.
Castillo Valdes and Rodriguez Sanchez worked together from Madrid, Spain and Havana, Cuba until 2018.
