Large Mid 20th C Bullicanti Italian Murano Purple Clear Bubble Glass Vase 12"

Beautiful mid century Murano Art Glass Vase most likely Bullicante Approximately 12" tall and 6 3/4" at the widest controlled bubble technique appearing clear to dark purple and then held up to the light, the color of grape juice! Mint condition, there is a hairline crack near the spout but it looks like it came from the process of making it because it is inside,it can’t be felt on the outside. Also, some black spots in the inside that I believe can be wiped off.
