Vintage Mephisto’s Magic Chest Cardboard Header?

Description

We acquired this from an old magician’s estate buy-out. Not familiar with this at all. Not sure if it was used with the actual trick or was the advertising/packaging header for the trick.

Maybe some collector will have a use for it.

Measures 5″ tall by 3-1/2″ wide with a 2″ X 1-1/2″ hole in its center.

It’s quite old and is creased in a number of areas but still a really cool-looking piece.
