I believe this dates back to when Tram opened up and on several different servers, shop npc's for some reason or another had available for sale, items mis-hued. I'm also guessing this was one of the very few items that got out in circulation and x-fered to wherever. As I said earlier though, I'd personally plop down several million for such an item if it were on GL, as I have already for many other mis hued Tram intro items..ie purple leg of lamb, strength potion, bowl of carrots and the such.
