One of the surprises for me about Dio de Los Muertos in Oaxaca was the tradition of making sand sculptures. Enormous sand sculptures. Some were easily more than 50 feet high and 25 ft wide.
Primarily red, blue and yellow were used but occasionally a golden glitter was added, especially when the drawing was religious in nature.
Some were pretty funny like this last one of a skeleton crawling out of his world and back into that of the living. Beer in hand, smile on his face, it looks like he just might make it back.
