This illustration depicts the tomb of Liliana Crociati de Szaszak in La Recoleta Cemetery, Buenos Aires, Argentina, which is known for its unusual neo-gothic design. Liliana was twenty-six years old when she was killed by an avalanche, and after his death several years later, her beloved dog, Sabú was added to her memorial. The text under the dog’s statue reads ‘Sabú, faithful friend of Liliana’.
