Appearances are deceptive. Picture inside box cover looks like that of an Escher. But the name Escher is nowhere to be found. The stone inside looks most like a coticule.
The outside of the box cover has the give away: Excelsior, Fienster Kuenstlicher Abziehstein, i.e. Excelsior, finest synthetic hone.
Take a good look:
