:oNice, I hope you won it! Anything that comes in that nice of a box is worth more that what it auctioned for. It really adds to the piece with the box and paperwork. I am very suprised that it went for that price and not wayyyyy higher.
I was examing some other pieces with Archimede Seguso signatures and they all pretty much look a like to me so I am wondering if it is by the same person, so chances are likely it was Seguso who signed. I do not know 100% if in fact it was himself who signed his pieces. I hope someone else knows for sure.
