Although this could absolutely be displayed like a diecut, it isn't actually a diecut. This is a remnant cut away from one of the exceedingly rare mechanical Rosen counter-top display sucker boxes. This was once part of a Rosen Owl Pops box. A complete example can be seen on page 116 of my newly published third edition.
