Vintage Big Arrow CO Santa W/ Toys Around A Mirror Unique Plastic Christmas READ

From a smoke free home, size is shown in the pictures. I do not know much about this, it is a hard plastic material, I am not sure if the mirror is glass or another material. marked Big Arrow. The bottom as seen appears as though it could have sat on something, maybe a round music box was my thought. Would be nice in a display, the colors are bright and it has a vintage look to it.
