Korean missing children cards

Korean missing children cards are card-sized posters of missing children that are/were included as cards in Korean Yu-Gi-Oh! booster packs whose information and design appear to be a hybrid of the layout of real Yu-Gi-Oh! cards and typical missing persons posters; they have information such as their name, the last time/where they were, how long the child has been missing and on the bottom of each card, a phone number and the URL of the official site of the Korean missing children database Like any other means of advertising missing persons, these card-sized methods are additional hopes in that consumers of these packs may know any information of these children to assist in their safe return to their loved ones.

Initial discovery
On March 5th, 2013, Kotaku, a video game website and blog, reported on how an anonymous user from a Japanese forum site named 2ch discovered cards that took on the style of legitimately missing Korean children from a Korean Yu-Gi-Oh! Ancient Prophecy booster pack. Supporting this find were users on the "Boosters in Korea contain images of missing children" subreddit, whom have said that these cards were also present in the Korean packs Extreme Force and Order of Chaos but not in Korean packs of Return of the Duelist. Furthermore the same reddit shows that missing children's cards were also confirmed to be in Korean packs of Generation Force.
