No person shall manufacture or mix for sale, offer or expose for sale, or sell under the name of raw linseed oil, or any compounding of the name raw linseed oil, or under any name or device illustrating or suggesting raw linseed oil, any article which is not wholly the product of commercially pure linseed or flaxseed. No person shall sell such adulterated raw linseed oil unless the package containing the same shall be plainly marked in legible black letters two inches high and one inch in width 'adulterated linseed oil' or without informing the purchaser at the time of sale that the same is not pure linseed oil; and the invoice shall accordingly read 'adulterated linseed oil.'
