The rabbit is a recent interpretation of the earlier Seguso pasta glass animals that I collect. These were originally made primarily in black and white, and occasionally in black and red, but none of the original production was done in black and gold to my knowledge. None were signed, but they carried the familiar scallop edged oval label from Seguso often accompanied by the circular red made in Italy label. The clear label on this was introduced I believe following Archimede Seguso's death which makes it about 6 or 7 years old at most.
If you want to see pictures of any originals, both Javier and I have examples.
