Product details
There is a very famous optical illusion with an illustration of two different sized and shaped boxes where one looks larger than the other. But when the tops of the boxes are measured, they turn out to be identical.
It was originally created by Roger Shepard and first published in 1990 under the name "Turning the tables", using tabletops, and that is why it is commonly known as Shepard Tables and the Shepard Tabletop Illusion.
In an effort to make the illusion play as a magic routine and to be able to present it standing up, the new artwork was placed on a steel board and the lids of the boxes were made into magnets. This allows you to visually demonstrate the illusion and take credit for the magic.
Comes complete with the framed illustration (12"x8"), two magnetic lids, and access to a video tutorial.
