As a sidenote, it is very probable that the guy was careful not to label shapes of his pictures directly, since the shape (in his opinion) would speak for itself, while naming it by an encrypted label would provide a clue to the decipherment. Hence it is quite likely that in many (if not most) cases labels do not stand for names of objects, but rather to some attributes. Like, an object may be a star (for example), but the label would not be the name of the star, but e.g. a word "good" or "bad" or "summer" or "winter" etc.
