Novelty give away advertisement for Maskelyne and Cooke’s Mysteries at the Antient Concert Rooms, Dublin. Commencing 4 March 1901

This advertisement can be folded to show The Box Trick in action. The words explain: ‘The performer enters the box which he completely fills so that no part can collapse inwards. It is then locked, enveloped in a sack, corded and sealed thus preventing any section giving outwards. Yet in a few seconds the gentleman escapes without disturbing a single knot, leaving the box perfectly empty.’
