Very nice Blenko Butterfly Decanter Design #6527 22 tall, with Blenko label. There is one stream of a water mark. I'm not sure if it's on the inside or the outside of the bottle. There is some wear on the base and some white, what looks to be scuffs but I think it's from water and with the flattened bottom.It's kind of unique. NOTE this is definitely on the outside of the bottle. This piece is absolutely a stunner and very clean. This would make a great addition to your collection.
