A miniature stage of two parts - a flattened but angled plinth support; and a detachable, convex, golden clamshell. Two tiny arms can affix to the back of the clamshell to create a stand-out mask/facade over the plinth. When the scene requires collapse, this section fits around the lower central half dome and obscures the red dome as a mask.
The cream background is probably flat, and the foliage is probably painted onto it.
The central figure is a carved ivory prop, and can fix to the top of the clamshell to stand or be suspended.
This figure can be God, or Jesus, or an angel, depending on the scene.
It could store fastened to the top of the clamshell.
