Bible Bank Book Piggy Plastic Hong Kong Black 1950's Collectable Red Stopper

I don't know much about these - I bought a small collection several years ago just because I thought they were cool. It's black plastic with gold foil lettering on the front - it's a sticker actually. It is a book look format.  There is no key rather a red stopper on the bottom. The stopper is marked very clearly Made in Hong Kong. On the side where the ? fake pages are it is also marked Made in Hong Kong. It measures 2.5 inches tall and 2 inches wide. Thickness give it an inch. It's in very good condition and of course the only one I have. I will get to the rest as well.

If I've forgotten something please don't hesitate to ask. What I lack in knowledge about things I try to make up with lots of pictures.
