Star Wars Darth Vader Halloween Costume 1977 Very Rare !

Star Wars Darth Vader Halloween Costume 1977 Very Rare ! 

I can't find any reference anywhere on the internet on this one, not even a picture. 

As pictured , it has a yellow square stain on the front and a tear under both of the arms , but other than that the picture is bright and clear. this is a very unique item. Imagine some little boy wearing this in 1977 , running from house to house. I consider this to be one of a kind.
