Every retail installment contract shall state the names and addresses of all parties thereto, the date when signed by the retail buyer, and shall contain a description of the goods sold which shall be sufficient for identification. No retail installment contract shall be signed by any party thereto when such contract contains blank spaces to be filled in after such contract has been signed; however, this provision shall not apply to serial numbers or other identifying marks which are not available for the description of the goods at the time of the execution of the contract.
