The advertisement from a Davenport catalogue shows the effect. The magician shows a sheet of glass held within a polished wooden frame. A playing card is placed on each side of the glass in the centre, the cards being held in place by the metal spring clips. The magician, and even members of the audience, can now push a rod right the way through the two cards, piercing the glass at the same time. The cards can then be removed showing that the glass is intact.

The magician magically removes a ring, or several rings, which had previously been placed on the rod. Complete with instructions.

In this very clever trick a single match box multiplies into a stack of matchboxes. The stack of matchboxes then mysteriously penetrates through a plate. Complete with instructions.

This is an old trick which is fully explained in Professor Hoffmann’s ‘Modern Magic’. The illustration shown here, which is taken from a Davenport catalogue, gives a brief description of the effect.

The magician pushes a rod through the box, at the same time as placing three large rings around the rod. The audience can clearly see the rings are around the rod. Despite the fact that the audience can also see both ends of the rod emerging from the box, the magician is able to take the rings off the rod.

This trick was invented by Brian MacCarthy. The performer is able to mysteriously pass a playing card through this wand. The wand is stamped DEMON on one of the white ends.

A ribbon is threaded through the square hole in the middle of the block. Each end of the ribbon is then held by a spectator, so trapping the block on the ribbon. Despite this, the magician comes forward and magically lifts the block off the ribbon. In ‘The Demon Telegraph’ of August-September 1937, Davenports advertised they were the only depot obtaining supplies through the sole concessionaire, Mr Brunel White.
