According to Blanca González Rosas, art critic of Proceso magazine, Sánchez Laurel had significant participation in the student strikes in Mexico in 1968 as president of the La Esmeralda National School of Painting, Sculpture and Printmaking. She was administrator and organizer of art from that school, safeguarding 65 original engraving plates from that time period, allowing for better understanding of the participation of artists, especially female ones, during the movement known as "Gráfica del 68."
