Need help on identifying a part on the New Gypsy

[maxheadroomyt]

I am currently working on remaking the gypsy seen on the live tour that joel did right before the pandemic. Does anyone happen to know where this part comes from? I have the carseat and flashlight (Both found at goodwill)

It kind of looks like the lid to a Rubbermaid or Sterilite type storage bin. They do make them in many shapes and styles, some specifically to store holiday decorations. Just a wild guess on my part.
