Cipher Wheel Code Booklet (#574)

To satisfy the spy in everyone, a vintage-looking covert booklet with a sneaky cipher wheel inside. Write and decipher coded messages using a substitution cipher method by turning the wheel inside the front cover. Write your message on the included notepad inside. To write messages with a friend, make sure you're both using the same cipher wheel, set to the same key letter. (So two booklets might be helpful, or more if you want to trade messages with a group.) Instructions are included on the first page of the notepad inside. Note for the curious from Christy: the cipher wheel (or code disk) was invented by Italian architect Leon Battista Alberti in 1467.

I first saw it in this book as a kid, which I still have!  Details Front: frame and dotted lines for labeling your booklet, printed in black or metallic silver letterpress ink Inside: cipher wheel for encoding and decoding secret messages, notepad with instructions on first page and 31 blank pages beneath
