Monsiváis argued that Rius has done a more important job in the promotion of reading than the official programs of the Ministry of Public Education, since thanks to him many readers have a general knowledge of subjects such as Marxism, the Cuban revolution or the institution of the Catholic Church. As Rafael Barajas El Fisgón says: there are those who have become vegetarians or worse (atheists, philatelists, anti-bullfighting and others) because of him.

Rius' friendship with Carlos Monsiváis is evident in the Museum's collection. The cartoonist donated to the Estanquillo more than 500 pieces of his work, including sketches from the magazines Los agachados and Los supermachos, as well as cartoons that he incorporated into his books and collages, some of which he included in the design of the pages of many of his publications.

The exhibition presents different periods in the cartoonist's production: early drawings, works by artists who influenced him and colleagues (such as Saul Steinberg, Abel Quezada and Alberto Isaac), his graphic vision of international and national politics that spans from the Cold War and its consequences in Latin America -when contradicting the dominant vision was a dangerous act of rebellion-.
