Hi Ray and Paul,
I really have a feeling this dog is not Seguso.
I have seen a duck, a whale, and another dog like yours before at auction saying it was Seguso, but looking at how the pieces are made, the fact that they do not have eyes, and the overall feel, I really dont think its a Seguso piece. Also the ones I've seen like this ahve a satin look to them.
If you look closely at the actual Seguso pieces, they dont have a satin finish on them.
Like Paul I also collect this pieces, and all of them, no matter what kind of animal it is has had eyes, and a little more work done, as far as the sculptural elements and shapes.
I also mentioned to Paul about a whale he was bidding on Ebay, that I saw the same whale on another auction months earlier described as a newer Scandinavian piece by the seller. So I think there is another set of these pieces around that are not Seguso.
Also, the Seguso pieces have a Blue color to the black, that you can see zip out onto the white. If yours is solid black, then I would worry.
Hope this doesnt bring you down, but wanted to mention it to you.
Javier
