The Golden Treasure Map is a decorative item for your wall and one of Cap'n Buck purchasable treasures.
The item came from Pirate Paradise and was available on May 2013 during the Pirate Takeover. It later became available as a coded item. It was sold again on 18th April 2014, as it was mistakenly put in the second wave of the wares of Pizza Paradise to promote the opening of the Food Factory.
X marks the spot! Treasure awaits?
