Topic: Murano Venini beaker, maker and age?

[Walewein]

Hello all. This is my first post on this forum. I noticed Murano glass is a highly specialised topic, I hope you can help me identifying, attributing and dating this piece.

I bought this murano beaker today, +/- 15.3 cms high, it has an acid-etched Venini mark, but I'd like to know who made it and when. The bottom shows some wear and the seller said he couldn't read the marks, that it was "old" and came from a house he had cleared himself. I'm not an expert in Murano pieces, but could you tell me something more on the designer and the age of the vase? Thanks in advance!
