It sounds strange to say it, but Day of the Dead is a holiday that is really fun. This is due in part today to the omnipresence of Catrinas, often life-sized dolls created by all kinds of people for display. The original Katrina was Jose Guadalupe Posada´s gift to Mexico. 
Posada (1852-1913) was a prolific cartoonist and illustrator who used
not just Catrina but skulls and skeletons of all sots and just about everything else in his political cartoons. Later nineteenth century Mexico, by the way, was home to quite a number of political cartoonists. Posada himself was a primary influence on Diego Rivera who hung around outside his studio in Mexico City to watch him work. Rivera included Catarina in his famous mural Sueño de una tarde dominical en la Alameda Central. 
In this section, you can see Diego, portraying himself as a boy, holding hands with Catrina and standing in front of Frida Kahlo.As were many of Posada´s cartoons, this mural is satirical, a lightish portrayal of social classes in Mexico.
Below are some Catrinas we snapped fotos of in Coatepec.
