This is a remade version of Viking’s Jack and Jill Jumbo which is an updated version of the Steve Dusheck and Jim Hill effect: Cases of Metamorphosis c. 1984. All of these effects are versions of Al Baker’s Cherchez la Femme.
This is a nicely made version, though heavier and not as fine as the Viking version. The addition of the separate stand allows you to show the cards in the stand before you begin so that you can show the cards and the frame cleanly to begin with. The holes to see the jumbo card through the frame could be a little larger.
