Scroll and Flower Panels - Imperial
Quite a rare vase with only a few selling. However, at the American Carnival Glass Association convention in 2022, these four vases were sold by Wroda Auction Services. They are purple, smoke, marigold and clambroth.

The original vases have a star impressed on the base like the one shown to the right on the clambroth example above.

They were reissued by Imperial. If the vase is flared or marked with an IG on the inside bottom, it's one of the newer ones.
