I cannot decipher the artist’s signature, although I have taken clear closeup photos of it. This is certainly in the Murano style of glass making. It was an estate sale find and no provenance was available to me. It is really beautiful and artfully made. The black rim around the opening is without chips or damage as is the vase body. Pretty waves of alternating yellow and clear glass and prominent “ribs” all around. It’s a beauty! Stands just over 5″ tall and is about 5.5″ wide. The top opening is 4 wide.
