CollectionZelda 25th Anniversary Treasure Chest
Game Title: The Legend of Zelda series
Set: Not part of a set.
Released As: Prize
This Zelda 25th Anniversary treasure chest was made exclusively for the 2011 Gamescom in Germany, to be given away as prizes at the event.
For a chance to win one of these chests, visitors to the Nintendo booth had to catch plush rupees which were thrown to the audience, which then allowed them to participate in a Zelda quiz called 'Zelda: Das Quiz'. Each quiz had a maximum of three participants, so each participant would end up with a prize at the end. First prize was a gold Twilight Princess Statue (the same as was available from Club Nintendo Europe). Second and third place winners both got a treasure chest containing 'secret content', with the third place chest being slightly smaller than the second place one.
This is the second place prize chest. It came with an Ocarina of Time 3D soundtrack, and an Ocarina of Time 3D 3DS pouch inside. The chests also apparently came with a Spirit Tracks bag, but I never got one with this chest (maybe the original owner kept it?).
A video of one of the quizzes can be seen here.
