The feather and bubble technique is called Sfumato.... I don't think this is a Cello piece, the quality looks too good. I know that many of the FM Konstglas pieces have a rounded triangular label and no engraving to the base, but I tend to agree with Ross here, that this is a V.Nason piece. The eye and beak show a craftsmanship that I have yet to see on Chinese birds and TK Maxx pieces, and the striped bird is definitely not the quality of yours Sue, so for the moment, until you see another, it is either Murano (V.Nason), or Swedish, (FM Konstglas).
I would have bought it.... it looks a lovely piece. If I see another, I will mention it here so you have a comparison.
