When I spent 3 months in Los Angeles some years ago I first heard about the Day of the Dead (Día de los Muertos). The holiday is celebrated mainly in Mexico and focuses on gatherings of family and friends to pray for and remember friends and relatives who have died.
Traditions include building private altars honoring the deceased, using sugar skulls, marigolds, and the favorite foods and beverages of the departed, and visiting graves with these as gifts. I really like the colorful and crazy way "death" is handled on this occasion.
The skulls were drawn in Steve´s moly from Moly_x_19.
