mod vintage limelight green glass cake plate or sandwich tray, Celestial starburst design

Vintage Federal glass Celestial pattern plate in lime green color, very mod! This rayed shape looks more like a flower than a sunburst to me, but it's really groovy either way, really. Measures 11 1/2" across.

This is in very good condition without chips or scratching, no signs or wear. There's a faint makers flaw INSIDE the glass, like a very faint shadow (see photos).
