Blue Spirit Wanted

Another poster from Avatar: TLA.

This one says: "Wanted, by order of the Fire Lord: The so-called Blue Spirit. He is a thief, guilty of stealing the Avatar from the Fire Nation. He wears a traditional Earth Kingdom opera mask. His true identity is unknown, but disregard the rumors that he is a ghost. If you locate the Blue Spirit and attempt to apprehend him, you are advised to enlist as many forces as you can gather for the task. - By decree of the Fire Lord."
