Antique religious 3D picture

Hello everyone. I found this at an estate sale last year. I just couldn't pass it up for the price. The frame is in wonderful condition. With the old wavy glass. It's in a box frame. With 3 different pictures depending on how you look at it. Also has paper flowers inside. Anyone ever see one like it? I'm not really into religion items. But this one is so interesting. Thanks for any input.
