Mid century mod vintage shell pink milk glass bowl, unmarked Jeannette glass.
This long low shape is perfect for a centerpiece, it's nice to have a shorter display for a dining table. And the pale pink color is perfect for spring and summer, or a retro holiday display.
It's about 17" long end to end. Nice and clean without soil or chips - it does have a makers flaw on the bottom (see photo). Line is only visible from the exterior, it's not right through the glass.
