Franklin D. Roosevelt Original Display Plate- Cracked

I was encouraged to go ahead and list damaged since this is a less common plate. It’s very fragile primarily due to a crack that runs diagonally across the plate. I took pictures - look on the front following how it shows clearly on the back. I haven’t glued or done anything to secure it. If you’re the next owner hopefully you know how to handle these delicate situations. Large dinner plate 10” Petrus Regout Maastricht plate, made in Holland. I’m guessing post WWII 1940s
