Calico Rose Corelle Corning ware glass counter saver, countertop trivet board

Tempered glass counter saver made by Corning, in the Corelle Calico Rose pattern. This measures 15" x 12".

There's no wear to the top surface of this piece, and just a few light scratches or marks to the design on the reverse. I believe these were mainly made during manufacture, since it's mostly at the spots where the feet were applied.
