Hello CathyG,
I have the same bowl in clear and gold, with the Balboa label.
Still unsure of who made it, since as with many import/export companies, Balboa has been a bit of a mystery. I do know about, and have owned pieces by Toso, Barovier, and Seguso with the Balboa labels. At least I think is a good quality piece so thats good!
Thanks Bill B for the info on the label!
