and here are the details
A board (19 x 21 cm = 7.5" x 8.5") holds a pad of plain paper. A spectator is asked to write a name, number, symbol, etc. on the paper. Of course, he does not allow you or anyone else to see what is written. The spectator tears the sheet of paper off the pad, folds it up and holds it. Instantly, before the spectator can even put down his pen, you know exactly what was drawn!
Imagine: You know exactly what is being drawn as it is being written! This is powerful, scientific magic. The exact image being drawn on the pad of paper is sent instantly to your telepathic notepad.
This is an improved version. The basic principle is that the clipboard has a built-in transmitter. An image drawn on the pad of paper appears on the display of a receiver you can be viewing elsewhere. The range is approx. 40 metres/120 feet! The display in the monitor has an integrated light, you can look at it in complete obscurity.
The transmission speed is very quick. This version has a numeric transmission not an analogic. You also have a reset function - so you can perform the effect as many times as you want!
