(NOT A REAL GAME)
This one of a kind CIB edition is HOLOGRAPHIC GOLD, with hand primed, painted and sealed with gold color on the vintage cartridge shell, holographic label and a warranty card/hatemailer.
This OEM Gameboy cartridge has been taken from an alternate timeline; extracted out of an expired dimension that God no longer supports.

There are only 15 Lessons of Darkness boxed copies ever to be made.
This is one of them. It's not a real game, it's a collectors item.

The absolute non-existence of this Herzog/Nintendo crossover in our local timeline is the essence of this carefully fabricated artifact that insists on the opposite. You can practically hear Herzog's smooth, yet indiscernibly thick German accent narrating this fake version of the experimental documentary that has been inexplicably adapted for the original gray scale Game Boy... which it never was, by the way. Not in this timeline, at least. In other words: this is a display only, inert cartridge.

The cartridge itself is a genuine original-equipment-manufacturer Game Boy cartridge (condition: primed, painted and sealed yellow with warning stickers).
Professionally designed and printed custom box, holographic labels, cardboard insert tray, and plastic sleeve for the box. The entire package is fabricated to resemble a legitimate commercial Game Boy software release of Herzog’s film. It is not an official Nintendo product and contains no playable Lessons of Darkness software. It's not an illegal romhack or homebrew. Asking if it is or not won't change that. The OEM circuit board in there? It's just some random Gameboy game (something like Tennis, Yu-Gi-Oh or Yoshi's Cookie) and is not tested.
Shipped in a real 6x6x6 inch box with bubble wrap and a 'Remembership card'.
