Operation decorations have a chance from dropping from a certain operation. Some drop from the random mobs, while others drop from the bosses. A 16-man will drop more decorations that an 8-man, and the harder the mode of the operation the better chance of a decoration dropping.
The Commemorative Statue of Dread Master Brontes decoration is dropped from the Dread Fortress Operation.
