  The reader is informed about a method for the objective identification of the
plane symmetry group of a "noisy" crystal pattern. Without giving numerical
details, this information theory based method is applied to two beautiful
pieces of graphic art. The plane symmetry group identifications distinguish
between genuine symmetries and pseudosymmetries as a byproduct. Pieces of
graphic/geometric artworks are ideal for the further refinement of the new
method because they are macroscopic and their '"noise content" is chiefly due
to the handiwork and employed creative procedures of individual artists. As
different graphic techniques/procedures were employed in the creation of the
classified crystal patterns, one may glean insights on how well a particular
technique or procedure supports the realization of a crystallographic symmetry
group in a graphic work of art.
