Dia de los Muertos, the Mexican holiday to honor the souls of the departed, is beloved for its macabre but festive decorations. But the ornate skulls, altars and folk art animals come from the humblest of materials: Day of the Dead decorations are traditionally just made from paper, flour and water, which combine to create paper-mache.

Some of the most magnificent paper-mache sculptures are created for a parade hosted by the Museum of Popular Art in Mexico City, which displays the magical beasts called “alebrijes” on the Paseo de Reforma, the city’s grandest boulevard. William Booth describes the Dia de los Muertos celebrations in Mexico:

Some of the creatures look like escapees from the H.G. Wells science-fiction classic, “The Island of Doctor Moreau” — such as an octopus lizard pig with talons and a whale’s tail; or a fever dream of Salvador Dali meeting the Cat in the Hat, painted in the bright swirling blues and scaled greens of Mexico’s southern state of Oaxaca, where the folk art form was born.

Paper-mache sculpture is a traditional part of Dia de los Muertos, and skulls, alebrijes, and ornate altars can be seen in celebrations from Brazil to California.
