Magic Wallet Book

This was my first attempt at a magic wallet book.

The idea is you place a card inside the book on top of the ribbons

and close it up. When you reopen the book in the opposite direction,

the card is magically held under the ribbons.

Close the book, open it the other way and hey presto!,

the card is now under the other ribbon!!

Unfortunately, I don't know who the creator of the chimp image is

and as I was only using this as a sample work I couldn't resist using it.
(I did do a bit of a google search but came up schtumm)

The playing card I found at a second hand store.

I inverted the chimp image on each reverse side to help me understand

how the structure works physically - brain still working hard!!!
