Magic Books versus Conjuring Books…

DavidPrice

On The Davenport Collection website which I mentioned and recommended a few days ago, I came across this funny bit in a fine article on “Booksellers, collectors, and rogues” by David Price (the British one) about the fine line between magic books and conjuring books, at least back in the Fifties:

Magicbooks

Love it!

I wonder whether similar “magic” code words exist(ed) in other languages as well?
