Molina Campos was a self-educated man. He never received education nor belonged to any artistic group that may have influenced him. He always considered himself to be a “folk draftsman” and never called himself either artist or painter. He had a deep admiration for the great painting masters and he was overwhelmed by their works, especially after visiting the major European museums.

“I must thank Providence –he said at one point- for allowing me to dare to insist on what does not pretend to call itself painting. Painting in the academic sense, namely, following and adjusting to the technique of Art. I only know that honestly and why not say, irreverently, I have tried to represent what has been peasant life of our Argentine plain as it is in our days.”

As for the materials he used, he started in 1925 with watercolor on drawing paper and followed later with pastel. Tempera was his forte. He finished his profiles with ink, to which he resorted to when he found it impossible to draw fine brush strokes. He also used oil. His surfaces differed;
he generally used papers and smooth or rough cardboard, cloth-covered cardboard, wood, chipboard and even ravioli box covers.

“My technique –he said- consists in eliminating details without hesitation that because they do not add anything interesting, only serve to saturate the painting and muddle its real sense. I emphasize what is characteristic and authentic in the gaucho and “his surroundings”, and I bring it almost to a stylizing point. When the gaucho sees himself thus represented he recognizes himself, he finds truth and admits it without distrust because I never show him in unrealistic situations”.
