Thanks to Kim for this one. The toy dates from the 1960s & according to a comic ad of the time:
1. Put a coin on the doorstep. Gears begin to whirr - light above door flashes.
2. Slowly the door swings open. A ghostly figure steals out - and covers the coin.
3. Suddenly the ghost spirits away the coin - and fades back into the house.
Having watched the video, I have to dispute the use of the word 'fades', but I must admit, it's still pretty good!
