This YAK has not yet been decided, but no matter how I stared at the picture - could not understand what is depicted here is not yet googled. It turns out that Moai (statue, carved image, the idol) — monolithic stone statues on Easter island in the Pacific ocean. At present, there are over 900 of them.
it is believed that the statues were made by the natives of the island between 1250 and 1500 years. The largest moai weighs over 82 tons.
