(a) In any instance where any bond, warrant, note or certificate is issued by any county, municipality, board of education or public corporation in this state and is required or permitted to be executed or attested by more than one person, a facsimile of the signature of any one or more of the persons or officers executing or attesting the same may be imprinted or otherwise reproduced on such instrument; provided, that at least one signature so required shall be manually subscribed thereon. In any instance where any interest coupons are attached to any such bond, warrant, note or certificate in evidence of installments of interest payable thereon, a facsimile of any or all of the signatures required or permitted thereon may be imprinted or otherwise reproduced thereon, and it shall not be necessary that any signature be manually inscribed on any such interest coupon. Any signature required or permitted to be placed on any such instrument for the purpose of attesting or authenticating the same, or certifying to the registration or validation thereof, or certifying to any other matter pertaining thereto, may be imprinted or otherwise reproduced thereon in facsimile, and it shall not be necessary that such signature be manually inscribed thereon. Any seal required or permitted to be affixed or impressed on any such instrument may be imprinted or otherwise reproduced thereon in facsimile.
(b) Notwithstanding the fact that, prior to delivery of any bond, warrant, note or certificate executed as provided in the preceding subsection, any of the officers whose signatures appear thereon should cease to hold office, such instrument shall be valid to the same extent as if the officers whose signatures appear thereon were serving as such officers at the time of such delivery.
(c) This section shall not be construed to repeal any other law authorizing the execution with facsimile signatures of, or the reproduction of facsimile seals on, bonds, warrants, notes or certificates for the payment of money.
