Given that Selbit is widely credited with performing the first "sawing a woman in half" illusion in 1921 this would suggest that The Radium Girl pre-dates many other well-known "big box" type illusions. Some sources give 1919 as the date when Walker first presented The Radium Girl. Known performances in more recent times include a presentation by English magician Jeffery Atkins at the FISM congress in Paris in 1973.
