Hi Guys,

I found this piece by accident. Does anybody have more info about this one? (date, ...)
I can't seem to find anything about this one except for the well known principle of course.

Thanks!

Peter

From the late 1950s or early 1960s would be my guess.
It's a common trick, hundreds of years old. There is no gimmick.

Thanks Richard!
