Clear Line, uses lines of uniform thickness(rather thinness) to show the outlines, the contours, the change of planes of the form, leaving out tones and other such details. The technique of 'feathering' used extensively by the great Alex Raymond is totally missing(no comparisons here.. Alex was a giant, his realistic rendering took comics art to grander levels). This produces in itself a certain clarity and hence simplifies the whole thing amazingly. Herge followed this clarity into the story line as well.
Herge used this style in all of his art, and went on to create a following in the comics creating world, spawing the use of Clear Line. Perhaps the most famous being The Simpsons..
