Flyer for Bathtub Piracy's festivities. This particular party takes place on december 5th, when the Dutch celibrate 'Sinterklaas'. Sinterklaas is a sort of Dutch variant of Christmas where a saint from Spain comes to visit our country accompanied by his black henchman called 'Zwarte Pieten' (Black Peters). They will bring gifts to the kids who have been behaving, but will put the naughty children in big jute bags and take them back to Spain. It's a Dutch thing... (and pretty weird when you have to explain it to foreigners)
