This is a Mid Century Modern Dolphin brand Beechwood casserole baking dish rack (or table trivet or caddy) made in Thailand in the 1970s.

It's perfect for serving oven-to-table baked meals such as lasagna, eggplant parmesan, tuna casserole, etc. and can hold any rectangular or oblong baking dish that measures up to 14 1/8" x 9 1/2", and can also hold a round flat-bottomed soufflé bowl of up to 9 1/4" in diameter in the center of the rack. It is both light-weight and sturdy.

The rack measures 16 7/8" x 10" x 3", and within the handles and curved ends, measures 14 1/4" x 9 1/4"

Note that the cranberry glass Pyrex dish is a prop for display purposes, however, if you would like the used (and slightly scratched) baking dish included, please state so in a message in order to make the proper shipping arrangements (as it weighs slightly over 3 lbs.).
