The possession of a special tax stamp from the government of the United States authorizing the sale or manufacture of alcoholic liquor as defined in this act by a person not licensed under this act, shall be prima facie evidence that the person so holding said special tax stamp is manufacturing or selling in violation of this act. A certified copy of such special tax stamp verified by the proper authority shall be admitted in evidence in all respects as the original special tax stamp might be received.
