This stunning mask is the sort that would be worn during Carnival or Mardi Gras celebrations, or perhaps for a glamorous masked ball. The colours are very Mardi Gras!
The colours of Mardi Gras are green, purple and gold, and beaded necklaces drape the route of the Mardi Gras parade and are thrown down to people from Mardi Gras floats. Here you can see a Mardi Gras mask, feathers and lots of draped beads!
You might find a "king cake" in many different countries, associated with the Epiphany at the end of the Christmas celebrations. The Bolo Rei in Portugal is a good example.
