This is the Bottom only to a Federal
Glass Art Deco style ribbed clear glass butter dish.
Measures 6 7/8” by 3 1/2”.

There are some flea bite type chips to the interior edge.
They are very small and may not show up in photos.
There are no big chips or cracks and this would make a great replacement if someone still has the domed lid.
This holds a quarter pound regular sized butter stick.
