I saw this vase at Salvation Army at least twenty years ago; it's graceful shape caught my eye. The glass is very thick, though, and it has an obvious seam along either side.
It took me a little while to figure out it must be a Good Seasons cruet. (For those who don't know, Good Seasons is a brand of salad dressing which comes with a packet of seasonings and glass cruet; you add the oil and vinegar.)
It also took me a little while to notice that when water is added, the "vase" is transformed and looks so beautiful.
Especially with roses.
