This was the first mural created using the spray-paint technique (it is worth noting that the Michelin piece was made with pasted paper). It represents the famous propaganda poster by Aleksandr Rodchenko (a 1924 lithography) and was executed by Paco Reyes in 2007. This work defined the aesthetic standards for all subsequent murals at the Faculty.

The goal was an aesthetic that, despite its realism, simplified the figures' shadows into a more graphic style, while still preserving the essential elements of their identity. The key lies in using flat colors whose juxtaposed shades create chiaroscuro effects, all based on a highly precise sketch that clearly defines the number of 'layers' or colors to be used.

In the words of Paco Reyes: 'In 2007, Professor Javier González Solas suggested I paint the Rodchenko mural (a symbol of advertising) in the hall, and so I did. It was straightforward: flat colors and a stylized graphic image. The sketch was already provided for me. This would go on to define the style of the murals created years later.
