An item was auctioned on ebay a year or two ago, and I wonder if anyone on this forum might be willing/able to tell me more about it.
The item was a plastic magic prop - I imagine along the lines of Tenyo - marketed to the world at large under Doug Henning's name; Jim Steinmeyer wrote the instructions. The seller described the piece as one of a line of seven different illusions.
This was before I realized I could print the screen for future reference, so all I have is my memory of the description. Can any of you good folks provide me with any more info about these toys? I would certainly be interested in acquiring them, but for now I'm merely seeking information. E.g., what were they called? When were they first marketed? Et cetera.
