The comic actor Cantinflas playing a naive scientist who is harassed by a corrupt chemical corporation; advertising the film "El supersabio". Colour lithograph, ca. 1948.

Plot of the film: the Mexican actor Cantinflas plays the research assistant of a renowned scientist, Prof. Arquimides Monteagudo (played by Carlos Martinez Baena). But Cantinflas (the character has the same name) has the soul of a poet rather than an industrial scientist, and wants to find the formula that will make roses live forever. After the death of Prof. Monteagudo, Cantinflas is chased by a ferocious corporation which wants to steal the secret formula of a cheap fuel (named "carburex"), under the illusion that Cantinflas is the only person who knows the formula (information from Internet movie database)
