Official Nintendo Seal

The Official Nintendo Seal, originally called the Official Nintendo Seal of Quality, is on the back of every current Nintendo merchandise of any kind. After the Video Game Crash of 1983, customers were wary of buying video games since most recent games were of poor quality. To counter this, Nintendo put Nintendo Seal of Quality on all of their merchandise.

Trivia

 * Cranky Kong often acts as a guide in Donkey Kong game manuals, complaining about the lack of quality in the games and stating they are not worthy of the Official Nintendo Seal of Quality.
