It is unlawful for any person who is not the holder of a license permitting the same, issued under the provisions of the laws of the state, or whose license has been suspended or revoked, to manufacture for the purpose of sale, sell, or possess for the purpose of sale, any alcoholic liquor in the city. The keeping in excess of one gallon of alcoholic liquors, as defined by this chapter, shall be prima facie evidence of an intent to sell the same. (Prior code § 3-16).
