Under the guidance of his teacher, Henri Ottevaere at the Academy of Saint-Josse-ten-Node in Brussels, where he enrolled in 1924, the young Van Lint began painting in a manner inherited from the realism, in vogue since Courbet, focusing on scenes of everyday life: interiors of the family home, still lifes, portraits of his relatives, views of areas of the suburb where he lives, landscapes he captures in his excursions into the countryside. As highlighted by the artistic press at the time of his first exhibitions, he already evidenced himself as a promising painter.
