The Fantastic Block
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.
