In the organization of PostEurop, special stamps with the EUROPA logo that every year has a unique central theme for all its members are issued. The theme for 2014 is folk musical instruments, Croatian Post Mostar will be presenting Herzegovinian pipes and dual flutes (dvojnice), instruments that were made and played by our ancestors, and are played till this day. Dual flutes or Herzegovinian instruments are in fact two flutes that are made from one piece of wood in that way both can be played simultaneously. It is most often made out of dry maple wood, plum, cherry, cornelian cherry or "kljen“ wood. Every hole has a labial opening, separated for a couple of centimeters from the above end, in which are located whistles from ash wood. The holes for screening are punctured in a parallel manner, on one side three or four, and on the other side four to five. The melody is always dual from the dual flute, and six tones can maximally be played from each octave. Croatian Post Ltd. Mostar has issued 2 commemorative postage stamps in a sheet of 8 stamps + 2 vignettes, a small sheet of 4 stamps, a postmark and First Day Cover (FDC).
