Small Silver Serving Platter with Lid & Handles, Mid Century, Classic, Elegant

This is a smaller silver platter with a lid and handles on it. I do not know for sure if it is real silver although it is on the heavier side and there is some discoloration to it like silver does. It could be cleaned up a little bit. There is a sticker on the bottom but I cannot read it. It measures about 12" long, 9" wide, and 3" tall.
