Across Mexico today families are carrying brooms, brushes, flowers, and food to local cemeteries. There, the living will tidy up and decorate the gravesites of departed loved ones.

Día de los Muertos, or Day of the Dead, is an upbeat festival rooted in the ancient traditions of Mexico's Maya, Aztec, Nahuatl, and other indigenous groups.

At Maria Vasques Hereda's tiny curbside stall at the Cuauhtémoc market in Mexico City, skulls in eight sizes and at least three flavors line the shelves.
Along with her husband, Vasques Hereda has sold skulls made from chocolate or sesame seed candy, along with other Día de los Muertos accessories, for the past decade.
"We conserve traditions and teach the children," said Vasques Hereda, who sells flowers from her stall the rest of the year and is the third generation of her family to market Día de los Muertos goods from the spot.

Office workers here in Mexico City, for example, will spend roughly five dollars (U.S.) during lunch breaks on tokens to offer dead relatives: votive candles, ceramic water dishes, or miniature braziers with charcoal and a jalapeno pepper ready to grill.
