David,
I am not implying that I think it is a Nymun piece at all, I was only using that as an example of a non Murano artist that used that style of controlled bubble work, and as an example of not associating it with a specific company, and more with individual artists.
I personally associate this type of tight bubble pattern with Scandinavian work, and not Italian. My general experience is that the Italian controlled bubble patterns are typically quite a bit more relaxed in appearance, and the bubbles are generally larger in size....
I am also interested in what others think, but I must say that the use of the green in that manner also reminds me much more of Scandinavian work than of Italian.
