One of the best versions of the Annemann's classic 'Seven Keys to Baldpate' effect. The apparatus is made in solid brass from a genuineSquire Old-English padlock. The lock is really impressive, being a mammoth 4 inches high. Six keys are shown and tried in the lock - NONE of them will open it. The seventh key is the only one which will unlock it. All seven keys are genuinely MIXED UP. A lady spectator's ring is locked onto the padlock. Six spectators each FREELY CHOOSE a key - there is NO FORCE of any kind. The lady keeps the key which is left and when she tries it in the padlock IT IS THE CORRECT KEY TO OPEN THE PADLOCK AND ENABLE HER TO KEEP HER RING. The mechanism is so clever and the working so simple that we know you will love this effect. Many different routines are possible with this superb apparatus.
