Every shipment, package, or container, containing potatoes which are packed, sold, distributed, or offered or exposed for sale or distribution in the state by any person shall be plainly and conspicuously marked with the name and address of the packer, or the person by whose authority the potatoes are packed or distributed, the net weight, and the proper grade of the potatoes contained in it. The party possessing the potatoes at any time shall be deemed responsible for the proper marking of the potatoes. On display racks or bins from which potatoes are sold in retail quantities, the proper grade must be plainly and conspicuously shown, but the provisions as to markings of name and address of the person by whose authority the potatoes were packed shall not apply.
