In State v. Roland, 88 N.C. App. 19, 362 S.E.2d 800 (1987), the Court held that the State had presented sufficient evidence as to the defendant's knowledge of the obscene materials and content because: (1) the defendant had been seen by a testifying police officer at the bookstore which distributed the obscene materials on two prior occasions; (2) "the box containing the film and the covers of the magazines were illustrated with pictures," with corresponding testimony from an officer that "these pictures were indicative of the contents of the film and magazines;" (3) "the jury had the opportunity to examine the film and magazines themselves to determine whether the box and covers reflected the materials' contents, as proof that defendant had knowledge of such." Roland, 88 N.C. App. at 29, 362 S.E.2d at 806.
