Help identify cut glass candlestick holders  

Art Deco or Postmodern?  You could almost flip a coin on it.  I'd argue for the latter, however, as it looks like these were made with more contemporary technology.

Look Italian 1980s to me, unsure of signature though.

Agree with Robert, they look like Italian Memphis design and the signature looks like it could be Marco Zanini but when I looked at his designs, I couldn't see a correlation.
At this point, I think they are probably some kind of American, contemporary reproduction but the signature is still making me think they might be Italian.
Jeez.  I sound like a politician.

Thank you EVERYONE for your help!

Quote by Ponzini from above link, which I found pleasing: "My work is definitely founded in my urban roots in New York City. I was fascinated with the city’s art deco buildings and modern architecture. More recently, on a trip to Milan, I was inspired by Italian contemporary design".
