All cemeteries in this State shall display a sign at each entrance containing letters not less than six inches in height stating "Perpetual Care" or "Endowment Care" or "No Perpetual Care" or "No Endowment Care" depending upon which method of operation the cemetery is using.
Those cemeteries which furnish perpetual care to some portions and no perpetual care to other portions shall display these signs on the appropriate sections of the cemetery to which the sign applies. Portions designated "Perpetual Care" cannot be changed to "No Perpetual Care" once the designation is made.
