This is one of my favorite Pyrex pieces that I own. It is a bit of a mystery as I have yet to come across an original box, the actual name of the pattern or the year it was manufactured. What I do know is that it seems to be a promotional piece. It has a white lid printed in a gorgeous mod floral pattern that sits on a 2.5 quart yellow base.
The base is a classic #475 Cinderella Round Casserole while the lid has no markings at all. This is unusual as most of Pyrex’s promotional lids have some sort of markings.
Type: Promotional Cinderella Round Casserole Series 470
Size: 2.5 Quart #475
