Nicely made plex board with pegs measuring 6 1/4" x 2 5/8" is shown along with an additional piece that is 3 1/2" for the purpose of writing upon with chalk or grease pencil.  Six disks with different numbers on each side are given to a spectator with the request they choose any three and hang them on the vertical row of pegs next to the hanging piece that will later be used to record numbers upon.   They are to write down these numbers (on the vertical piece) and are then asked to remove one and turn it over and record the number on the opposite side underneath the first three and discard this.   They are now asked to choose another disk from their hand hanging it on the vacant position.  This number is then written down on the pad below the other numbers.  They are instructed to keep the remaining three chips in their hand hidden and to turn the vertical piece with numbers over so the performer cannot see the random selection assortment.  The performer now concentrates and writes a prediction on a paper or the backside of the vertical strip or the backside of the board.  After the prediction is made the vertical piece is turned over with the request the numbers be totaled.  The prediction is revealed and it matches!   This is a nice vest pocket prediction.  Includes illustrated instructions in English language.  The instructions also mention that you may wish to write the numbers upon little paper strips instead of the vertical piece.  Condition First Rate and Scarce.
