Satan Writes

This is a ‘Vampire’ trick from Max Andrews. A spectator takes one card from a packet of examined visiting card blanks. On one side of the card a panel is printed together with an image of the Devil himself. The spectator signs his name in the panel, seals it in an envelope and puts it in his pocket. Despite these precautions, the name of any selected card will appear in blood red letters on the signed card. Complete with instructions.
