§ 306-6. Presumption from display of prohibited publications.

If any publication prohibited hereunder shall be displayed in any newsstand, bookstore, drugstore, market or other mercantile establishment where said prohibited publication may be seen by any child under the age of 18 years visiting such establishment, such display shall be prima facie evidence that the person in charge of such establishment was then exhibiting the crime "comic" book or other prohibited publication and intended to sell, offer for sale, furnish or attempt to furnish such prohibited publication to a child or children under the age of 18 years in violation of this chapter, but it shall be competent for the defendant in any such case to show that no such intention existed.
