Whaley credits Jardine Ellis with this effect, citing Eric Lewis having seen it performed in the 1920s. It appears in Magic and Its Mysteries by W. H. J. Shaw (1893) as “To Produce a Glass of Liquor from a Handkerchief”. Shaw's method does not use a rubber cover or plug; rather, he employs a harness arrangement similar to that used in the Carlo Glass Production, c. 1940s. This, then, is a precursor to the now-standard Pollock-style dove production. Carlo used the technique for the production of a rather large glass, kept in the performer's back pocket. Shaw steals the glass from the back of a chair, but the harness set-up is essentially the same.
