Completion Certificates

From Ultima III to Ultima VII, players were told to report to Lord British after they'd won the game.

While this seems strange today, back then it had a real use. Reporting to Origin that you won the game resulted in a Completion Certificate in which the player's name was entered being sent over mail. These certificates are today highly sought-after collector's items.

The certificate to Ultima VI is special since it also contains a message on Gargish. Translating it should be real hard work...

Also, when the special Dragon Edition of Ultima IX came out, it also contained a certificate from Richard Garriott, in which he thanked the players and hinted at his future ambitions (this was before EA managed to make him leave).
