Signage in Tennessee

I was reviewing the signage laws in Tennessee and need some clarification, specifically 39-17-1359.At first it says, "(3)(A) If a sign is used as the method of posting, it shall contain language substantially similar to the following: AS AUTHORIZED BY T.C.A. § 39-17-1359 , POSSESSION OF A WEAPON ON POSTED PROPERTY OR IN A POSTED BUILDING IS PROHIBITED AND IS A CRIMINAL OFFENSE."But then it says, "(C) A building, property or a portion of a building or property, shall be considered properly posted in accordance with this section if one (1) or both of the following is displayed in prominent locations, including all entrances primarily used by persons entering the property, building, or portion of the property or building where weapon possession is prohibited:(i) The international circle and slash symbolizing the prohibition of the item within the circle;  or(ii) The posting sign described in this subdivision (b)(3)."So which is it? Is a slash sign enough or does it need to have the specific wording?Edit: it just doesn't make sense to me for there to be a strict statement and then them say, "nah, a picture will be good enough" via /r/CCW https://ift.tt/2lIXNOl
