Tupperware Vintage Medium-Large Covered Serving Tray
I love this item and its the first time I have seen one. It's a good size, I would say medium to large. A covered serving tray with a domed lid.
This is a vintage item, unused and in like new condition. A rare find indeed. I would love to know what this is called. A small cake would fit in here, as well as scones etc.
