Actually I once saw a finial in a dragon shape. Two reasons I didn't buy it although I really really wanted to... I looked at all my lamps and could not find one where I would be able to SEE the finial. Then there was the price, plus the shipping!
Had I a place to show it I think I might have talked myself into the price and even the shipping costs but... I buy things that, if they have a purpose they must be used for it. So it would
have to go on a lamp which I would then not be able to see it...

doesn't work for me.
I also drooled for
days weeks over a cast iron dragon (think it was somewhere in Virginia). Was a pot to put on my wood stove for moisture. Again, price and shipping put it waay out of my pocket book. Although, had I still been driving the snow bird cars to FL... I would have stopped and gotten one for sure
