Schetches are those drawings that are made in a short time at fairs or as a preliminary or study, of an illustration to be made definitive. The sketches are often done only in pencil or with a few touches of ink to define them a little. They may have some halftone or some shade of color. Many fans believe that the black and white and preliminary drawings are more beautiful than the final, for that feeling of “unfinished/finished". They are "naked" drawings that we can compare to acoustic or folk versions of rock songs.
