Recently I read in some of those really old books in magic. In the volume “Tricks for Everyone” by David Devant (published in 1909!), he describes a lovely quick trick with a ruler.
The moves and the vanish look like the well-known “Flip Stick Move”, as a glance at the illustrations will prove. Amazing, what can be found in those old books!
And just another proof, that most of the important stuff in magic was already invented or thought of before …
