Every instrument, to which it is required or permitted by law that a seal be attached, shall be deemed to be sealed when there is affixed thereto, or printed, impressed or marked thereon a scroll or other device by way of a seal, and no such instrument shall be impeached or questioned for lack of a wax seal. This section shall apply to sealings by corporations as well as individuals; but any sealing required or permitted by law of a public officer, board, body or commission having an official seal shall be by the impress of such official seal.
