Emile Henry - France blue & white ceramic casserole or au gratin baking pan

Emile Henry made in France ceramic gratin pan, 12 1/2" across the handles. Not sure of the vintage on this one, I know these have been sold at Williams Sonoma for years.

This one is in excellent condition, I don't believe it was ever used. Nice and clean, glossy without scratching. Love that classic blue and white color, too.
