(1) Any persons owning any works of art which are apt to be displayed in any county of the state during any calendar year shall indicate in a statement accompanying their personal property schedule the kind and description of such works of art and the estimated period of time during the calendar year in which such works of art are to be so displayed and shall provide to the assessor proof of exemption pursuant to the provisions of sections 39-3-123 and 39-26-102 (2.5). Failure to file a statement results in forfeiture of a claim for exemption in that calendar year.
(2) The assessor of the county in which such works of art are displayed shall determine its value in the proportion that the periods of time during which such works of art may be displayed bear to the full calendar year. He shall furnish a copy of such valuation to the owner of such works of art or to his agent.
