The man behind the Miracle Series was Barrie Robin. He put out a series of tricks, jokes and magic in the 1950s. The instructions explain that this is The Famous Chinese Fire-Eating Trick with which you can produce sparks and smoke from your mouth. This doesn’t seem to be an appropriate trick for the younger purchasers at which this Series was aimed. The comment that “Reasonable care must be exercised” seems an understatement. The back of the packet contains a list of other items in the Miracle Series. Gus Davenport supplied Barrie Robin with some of the products in the Series.
