Frank beat me to it but I'll post this anyways.
Hi, the quoted information is from a listing selling purported Dante Veni glass, priced so high it hasn't sold since it was listed in 2008.
There is no other information on this maker on the first five google pages before they're filled with Dante Alighieri's and Veni vidi vici etc.http://www.goshop2day.com/Muano_20_Glass.html
The fact that the signatures are identical only indicates a standard etched mark, ie not signed by the maker but etched in by use of a template.
My personal theory on this is that Veni is very similar to the very well known Venini and could be confused for Venini by novice collectors.http://www.venini.it/eng/home.htm
The same vendor has glass by Mauro Cendese, very similar to the much more famous Cene
dese family name - misspelt throughout and the labels all too blurry to read.
After collecting glass for a while one learns to appreciate that signatures are easily added post facto and are meaningless unless the piece corresponds to the artist or maker
the signature indicates, I have seen many many Chinese/Muranese paperweights labelled Baccarat (a popular forgery).
I am confident the paperweights in this thread originated in China based on the canes used, the colors, the workmanship, the lampwork.
