This correspondence debates a theorem formulated by K. Sugihara in a recent publication. The theorem deals with the mathematical structures of line drawings, and serves as a basis for a substantial part of the paper. This note claims that the theorem as formulated is not valid. The claim is substantiated by a counterexample.
