Vintage Antique Blue Corn Flower White Milk Glass Divided Server Casserole Dish. I believe this to be a Glasbake piece but it is unmarked. It does have the round circle and bubble bottom. Condition is "Used" and overall very good. There is the tiniest flaw on the edge where it feels rough (see zoomed in photo) that can hardly
be detected. Please feel free to reach out if you have any questions. Shipped with care USPS Priority Mail or whichever is less expensive per your location.
