|Three Footer (Tre Fotter), Eda|
I'm aware of these in only this shape; three feet with a sort of star and arch pattern on the exterior. The interior is plain. Identified by Glen and Stephen Thistlewood in their book, A Century of Carnival Glass. They show them in blue, a lilac shade, and a marigold like this one. Figure values at $40 to $50 for the marigold, more for the other colors.
