The poster advertises the IBM British Ring show at the time of a Northampton convention. The bill includes George Davenport “Magic of 1933”, the man who swallows razor blades.
This was a show from the British Ring No. 25 of The International Brotherhood of Magicians. Although Lewis Davenport is shown topping the bill, he did not appear as he had a week’s engagement in Northampton. George Davenport appeared in the show. He is billed as Gilly Gilly in magic of 1932.
