Over the years, Van Lint's plastic composition expands, is cleaned, and is laid bare: the articulations are more flexible and unbound; the luminous colors always opt for agreements that are less confrontational. Through the passages of colored plans beautifully orchestrated - which Van Lint called "the seams"- the artist is unparalleled in dissolving the graphics and the general construction in the color.

He continues however to find the key to his compositions not in the pure imagination, but in this valuable loot he gathers in his persistent diving everywhere where he is touched by a climate, the color of a land, the playful waves, the changing shapes of a sky, the morphology of a plant, a seasonal metamorphosis. In 1974, the year he must undergo the removal of a large part of the stomach, Van Lint is honored with a tribute exhibition at the Palace of Fine Arts in Charleroi.
