I would not call this Murano glass. It's molded and not blown (the raised Made in Italy and mold line are telltale signs). Plastic under the stopper also indicates inexpensive, mass produced glass (circa 1970s Pier 1?), although I do have a couple of Eric Hoglund "people" decanters with these plastic tipped stoppers that are blown glass. Nice set all the same, definitely have that retro Austin Powers look. I think it would be nearly impossible to identify the maker.
