"Catrinas" - uniquely Mexican figures depicted as richly-dressed skeletal women. (Dead ones - not Nicole Ritchie.)
The "Day of the Dead" is celebrated in Mexico and around the world on 1 and 2 November, corresponding with All Saints' Day and All Souls' Day in the Catholic calendar.
Days of the Dead celebrations actually pre-date Catholicism and have been around for at least 2,500 years. They can be traced back to the Aztec festival honouring the goddess Mictecacihuatl, "The Lady of the Dead."
During these days, families honour and commune with their deceased relatives, offering their favourite foods and drinks, placing marigolds ("The Flower of the Dead") on their graves and sometimes sitting at gravesites all night.
What a cool way to remember lost loved ones.
