Large 1960s Vintage Christmas Ornament Glitter Diorama w 4 Angels Singing

This is a vintage Christmas ornament that is made of glitter covered styrofoam. There is an open window on each side, revealing a plastic angel singing from a book that is printed with Noel (the angels dont actually sing). It measures 6 square with a height of 7 1/4 - it sits on three ball feet. It is in very good condition - just a bit of glitter missing from one of the feet, really minor. There is a gold ribbon on its top and a loop for hanging the ornament, if desired. I believe that this dates to the 1960s and was probably made in Japan. Very pretty - nice addition to a vintage Christmas decor!
