Cut the postcard into 3 pieces. Where does the 13th card go when the position of the two lower pieces are reversed? The LD letters on the postcard tell us that it was produced by or for L Davenport & Co. See the advertisement from a 1930s Davenport’s catalogue. The white space at the bottom right of the postcard would be used to print the name of the person or company that used the cards for publicity.

This electrically driven illusion was made in 2014 by Cambridge magician and engineer Tony Middleton for display at the British Magic Museum. As the spiral rotates it appears to move upwards with the two crystals suspended in space. A commercially available spiral illusion was used.

A piece of thin cord is examined and passed twice round the centre of the rod. The two ends of the cords are held by members of the audience, yet the cord comes away free from the rod on the command of the performer. The rod may be examined.

This brass and mahogany trunk is of the type used by the Maskelynes in the sketch Will, the Witch and the Watchman. The Davenport family bought the assets of the Maskelyne business in the 1930s. This trunk was found in a canvas cover labelled Clive Maskelyne, South Africa. Clive did indeed tour South Africa, so this is probably the trunk he used. It certainly shows signs of wear and tear.
