vintage ebony black / clear glass tumblers & sherbets, Weston lily pad waterlily flower foot

Vintage drinking glasses and sherbets or dessert dishes with crystal clear bowls and black glass flower petal shaped foot. These are Weston glass, I think?

There's four each of glasses about 4" tall, and sherbets about 2 1/4" tall. They're all in very good condition without damage or wear.
