Ted Annemann's writing in Jinx No. 19 alludes to an obscure Al Baker manuscript that Annemann had seen when he was 17 years of age, at which time the manuscript was already old. The manuscript contained some of the first writings by a well experienced and well informed magician. It was called Al Baker's Mental Effects. This was a remarkable collection of ideas and fabulous routines aimed especially at the mentalist/magician. Although it featured Al Baker's Billet Reading Extraordinary, each effect in the book was a feature item.
