This wonderful effect was invented by Al Baker c. 1932 using a simple but extremely effective method. P&L were the first company to manufacture a version of Mr. Baker’s effect and it remained the gold standard for decades afterwards. The method was first described in Greater Magic c. 1938 (pg. 512). and it is also discussed in Dr. Albo Vol. 3.
The method has been used in many other card effects over the years and a few of them can be seen here.
Two of the good features in this P&L version are the stand is easy to swivel around so that the audience can choose the queen without any fumbling and the backs of the gimmicks are cleverly painted to blend in to the stand.
