Jose Guadalupe Posada was a Mexican illustrator whose engravings of satirical calaveras have become permanently associated with Day of the Dead imagery and literary culture.

To celebrate the holiday, photographer Tim Tadder made the Las Muertas series. Each of the models represent one season: Winter, Spring, Summer, and Autumn.

The best activity you can undertake for the Day of the Dead is to create the traditional altar, or ofrenda.
