A friend of mine just shared this interesting thing with me:
From the blog graffitimundo:
The walls of Buenos Aires have paid homage to Nestor Kirchner in various ways. In the immediate aftermath of his death, the words ‘Siempre Nestor’ were splashed across the city. To mark the one-month anniversary of Nestor Kirchner’s death, the political group La Campora distributed stencils to activists in every barrio of the capital, and the image of ‘El Nestornauta’ began to appear throughout Buenos Aires and beyond.
El Nestornauta is a combination of two images – the face of Nestor Kirchner, wearing the suit of the classic Argentine comic character “El Eternauta“.
