I regularly seek out old books because a) I'm cheap and you can often find old books for free on the
internet archive, and b) the best tricks are in old books. This was one of those rare instances
where I read about it, and couldn't find it in the archive, and all the magic shops I checked were
either sold out, or charging twice as much. Having purchased it and browsed it's selection of
bizarre offerings, I would willingly pay three times as much if I had to buy it again.
