"World's Best Psychic Book-Tests" and "Premier Book Test", (Burling Hull), is shown here in early manuscript form.

"Volta" is the name Hull used for his work in mentalism. The "Premier Book Test" manuscript includes an even dozen book tests.

The "Psychic Book Test" is classic Hull, described by him as follows:

"The beauty of this test is, that throughout the experiment the performer apparently does nothing whatever, and TOUCHES NOTHING USED IN THE TEST. The material used can be thoroughly examined after the experiment is finished. There is the advantage of being able to use ANY MAGAZINE OR BOOK DESIRED. The cards used are an ordinary pack of cards. There are several subtleties which are practically unknown to magic previously."
