Vintage Steuben shops glass footed crystal bowl; signed.

Product Name: Vintage Steuben shops glass footed crystal bowl; signed.
The bowl is a semi circular shape. The base shops is a heavy blob like glass that has three major pinched in sides. Then there are other pinched in sides between those and less severe. As I have the bowl upside down, it looks like an abstract three leaf clover. The glass is in good condition with no chips/cracks. Some scratches on underside from years of wear. Also signed Steuben in the middle. Inside bowl, has some scratches, a few cut like scratches but not bad at all. There is a faint circular scratch line in bowl's perimeter; faint in nature. I have seen this in bowls before; could be from production; sold as I found it. A few exterior light scratches. Nice condition considering age. Measures 10" X 4.5".
