Whenever I see a pic like this it brings back memories of the number of short stories Ray Bradbury wrote about this day. "El Dia de Muerte", "Candy Skull", "Next in Line" ,"The Life Work of Juan Diaz" etc.
Aguascalientes is the city in which José Guadalupe Posada lived and worked.
Many of the skeletons in Mexican art were created by him and it is appropriate that the Museum of the Dead be in Aguascalientes.
