"Au Gourmet", amber glass, divided serving platter

I've had this dish (2 of them actually) since the early 70's and acquired them from a yard sale. They are quite heavy and measure 10 1/4 inches across by 1 inch high.

I've enhanced the second photo to show the detail in the center. There are no other marks than the emblem and the words "Au Gourmet". The plate is on a stand in the first photo.

The color is amber.

I haven't been able to find out anything about them. Any input?
