Bishop surely knew what he had in Steinmeyer, and wanted the audience to know as well. He informed us that many of the illusions he was performing in the show could not, and would not, be seen performed by other magicians. This sort of prideful boast is not unusual for stage magicians, and in fact is a practice that goes back to the golden age of magic (late 19th and early 20th centuries), when magicians such as Harry Kellar and Thurston would compete for (and often steal) each other's illusions. Since magic has no copyright protection for its methods, even today, gems created by masters like Steinmeyer are closely guarded and pridefully presented.
I was delighted to see Bishop perform a rarely seen Steinmeyer illusion called "Op-Art." where a woman climbs inside a box on caster wheels that closely resembles a portable computer laptop cart. Door-by-door, it is revealed that she has vanished, except, impossibly, for her head. Bishop then proceeds to turn the entire unit around for viewing, until even the head is gone. Steinmeyer is a modern master of the magic cliche, "It's all done with mirrors." However, even with that clue, seeing this illusion live and up close was truly baffling.
