Avon Vintage 1995 Large Christmas Stocking Plays Music Santa Gift Bag Tree

Vintage 1995 Avon large Christmas stocking- 29" diagonally and 15" across the top small mark on the back as shown in photo This plays the tune "Santa Claus is Coming to Town" with music box sewn on the inside. The music currently works and plays fine but I don't know how long it will work for or if the batteries can be replaced when they wear out, as the box is sewn into the lining.
