The complete restoration —using the “tratteggio” or “rigatino” technique— of the “El vaquero” (The Cowboy) painting, by French artist Victor Emile Cartier, is exhibited in seven superimposed canvases. The 1853 painting is the oldest in the collection of the Museo Nacional de Artes Visuales. “Tratteggio” is a restoration technique based on the juxtaposition of small lines or strokes of color. These lines are visible from up close, but when observing the work from a distance they blend in with the original layer. In “Informe de la restauración”, the “gaps” and damages in the Cartier painting are reintegrated, but the colors of the restoration are separated into each of the seven canvases.
