The Noah’s Ark shown in this film is the Oswald Williams illusion which the Davenport family purchased in the 1930s. The illusion has rarely been performed since that time. The performance shown here was in the Gala Show at the First Pentacle Club Magic Convention held at Churchill College, Cambridge on 29 June 1980. It was performed by Pentacle Club member John Whitmore. John was a school teacher, which was very useful because the illusion requires a large rehearsal space and he was able to make use of the school hall. The show was compered by Jack Delvin.
