Any bank has a lien upon the shares of any stockholder of the bank or any stockholder of the parent bank holding company who is indebted to it, and for such purpose, in addition to stock duly recorded, the bank may enforce its lien against stock actually owned by the debtor but not recorded on the transfer books. All certificates for such stock shall have printed or stamped thereon the words: "Subject to lien for any indebtedness of holder to bank," and such lien is not enforceable against a purchaser in good faith unless such words are printed or stamped on such certificate.
