His lithographs and etchings belong to the Dutch movement of New Objectivity. Prange focused on architectural forms and desolate urban ruins. His style is marked by a cold, surgical precision. He avoided soft edges or decorative flourishes. The compositions often feel silent. This approach creates a sense of unease found in Magical Realism.

Collectors today value Prange for his stark aesthetic and mastery of the lithographic stone. His work offers a quiet alternative to more colourful movements. The monochromatic nature of his prints suits minimalist home decor. His focus on structure makes his pieces look modern despite their mid-century origins. Each print shows his dedication to traditional draughtsmanship.
