Your Mexican figurine is just wonderful. I have one that is made by Oball. Many modern Murano companies make these including, Formia, Oball, Andrea Tagliapietra and I am sure there are others. They are copying the Seguso design. Andrea Tagliapietra is considered to be a more modern Murano name. I do believe Andrea Tagliapietra is the maker of your figurine. Nice find!
