I have several of these masks from traveling to the Philippines. They are used in an annual festival that occurs in my wife's hometown. There is a lot of art there in the markets that is not so commercialized - here even the "crafts" of old are being blisterpacked.

The Masskara Festival in Bacolod, Negros Occidental, the capital city of the Philippines' sugar producing province takes place during the week of October 19. The festival's name comes from the word masskara meaning many faces and mask. It is a festival of masks that is a feast for the eyes that excites and invigorates.

The Masskara Festival was created by the Bacoleņos to fight and uplift their moods in the time of growing economic depression on the island in the 1980's. It has become an annual event, one of the liveliest festival that attract many visitors to the land of charming Bacoleņos.

The Masskara Festival is touted as the Negrense version of the Mardi Gras of Rio De Janeiro, Brazil. Festival highlight is the street dancing of the people wearing colorful costumes and smiling masks.

Conceptualized in the 1980's to enliven the celebration of the founding day of the city, the Masskara Festival flaunts the festive spirit of the Negrenses inspite of the slump in the sugar industry. Aptly symbolized by a smiling mask, the festival succeeds in alluring tourists and sightseers, boosting the city's tourism.
