A bold and geometric abstraction rendered in acrylic on canvas, *Athabascan IV* reflects Ludwig Sander's signature approach of arranging flat, precisely edged planes of color within a carefully structured composition. The work's restrained palette and clean divisions of form demonstrate Sander's alignment with the hard-edge painting movement, evoking a sense of quiet tension and balance. Housed in the artist's own frame, the piece underscores Sander's deliberate attention to the total presentation of his work as an integrated artistic statement.
