Natalie Morrell brings to my attention photos of Catholic shrines crafted by French soldiers during World War I. These contain images of the saints for veneration during traumatic and terrifying times. Many remain, floating around antiques dealers. They're shaped from dispensed brass casings from rifles or field artillery shells. Many of these sculptures display remarkably professional skill and precision, as detailed in Nicholas J. Saunder's book Trench Art, A Brief History and Guide, 1914-1939.
