Topic: Vintage glassworks to evaluate. Help!

[Artofvenice]

Hi,
I have just received several glassworks from a Murano friend. he would like to sell them, but before to offer them to the "public", I would like to verify an approx. value  :huh: of these pieces. I know that sometime can be hard to give an exact price for this kind of glassworks, but I would need at least a price range. Some of them should be really rare and I know that they are original (they came directly from the original company due to the father worked for Venini and for Barovier) and in perfect conditions.
Every info and opinions would be very useful.

You can see them in these pages:

and http://www.artofvenice.com/art/murano-vintage.asp

Thank you in advance.

Sincerely

Alex
