Vintage Waechtersbach Winter Dreams Collectible Coin Bank

Vintage Waechtersbach Winter Dreams Collectible Coin Bank Excellent condition The only problem is that I don’t know how to open the bottom. I don’t have a key and have no idea how it works. It’s beautiful and if you are a collector, it’s perfect! If you’re wanting to put money on it then I hope you know how it opens. Also, feel free to lmk how it works if you know. :)
