Hi. I am basically joining this group because I do love glass and I have several vintage things from my parents' estate that I need help identifying. I'd like to start with this one--a vintage corset vase that's probably 50 years old. I've done lots of research, but I can't figure out who the manufacturer is. There are lots of corset vases out there, but most have a sunburst on the bottom whereas this one has a flower. Any ideas?
