More labels:
Click on thumbnails to enlargeThe first is a uranium green vase 8½" (21.5cm) tall. Strictly speaking I don't think this is Murano, but 'Venetian'. The label (badly ripped) merely states 'Venetian Art [Glass?]' and is situated on the neck. It also has one of the small circular 'Made in Italy' labels on the base. The central portion of this label has a tiny logo that looks like a 'G' with an 'H' in the centre, so either 'G.H' or 'H.G' is the maker?

The second is a clear plastic label, with gold lettering. On the left side is written vertically 'Murano', with 'Vetreria Artistica' and 'OBALL' to the right. Any clues to the maker?

:

The label is shown twice, as the backlit version shows the lettering clearer.
[edited to correct spelling on label: "Vetreria" with the last 'a' - label not terribly good!]
