Demon Wonder Box – made of copper
The box is shown empty and then a number of handkerchiefs are produced from it. This was a very popular trick first marketed by Davenports in 1934. The inside lid of the box is stamped with the Davenports demon head logo and the registered design number: 791997. Davenports purchased the UK rights from Janos Bartl in Germany, who invented the trick. Bartl sold the trick under the name ‘Silkwonder’. Davenports usually sold a nickel plated version (see Ref. no. N46) but as a result of shortages of metal following WW2 some were made out of copper.
