Henk, i know similar discussions have taken place before, but why on Earth would you not consider the Madura keris "authentic"? The sheath carving certainly has little to do with traditional style Madurese wrongko of the, say. 19thC, but this style of carving IS very much in Madurese and i would accept it as a tradition piece for the late 20thC. I certainly wouldn't brand this a "tourist keris", it's just not an "old" keris. It is a decently executed blade, certainly not tourist junk. It is a modern keris for the modern keris collector. Why should we have to wait another hunderd years to accept that (you know....when it becomes old).
