All these years I've been wondering about the meaning of these two polygonal symbols painted on the vessels or tanks located in the room where Vader chokes Captain Antilles, at the beginning of Star Wars: A New Hope (1977). The logic dictates that they are signs that represent what is contained inside the containers, but to me, they also suggest something else, like pieces of a Tangram. I have been playing around with them and my best explanation is that they are a hidden logo of the starship's name. Putting together the two symbols, one above the other, I get the letter T but depending on the point of view, someone could say that it is the shape of a robot or perhaps a hidden clue? Anyway, I ask if someone out there have noticed these symbols and have a possible/potential Canon/Legend explanation for their existence in the Star Wars Universe. Thanks.
