This powerful 1975 Belgian semi-postal stamp depicts Saint Dymphna, the patron saint of mental health, in a dramatic medieval sculpture scene from Geel. The design shows the moment of her martyrdom, rendered with rich, gilded tones that highlight the spiritual and artistic heritage of Flanders. Issued with a charity surcharge, the stamp supported social welfare initiatives and reflects Belgium’s long tradition of religious-themed semi-postals. A compelling piece for collectors interested in Christian iconography, Belgian charity issues, and regional devotional art.
