(a) Bonds, notes and revenue notes, other than uncertificated obligations, shall be executed on behalf of the State by the issuing officers and shall bear the impression, or a facsimile, of the Great Seal of the State. All the signatures of the issuing officers may be engraved, printed or stamped on bonds, notes or revenue notes notwithstanding any other law to the contrary but no such signatures nor the impression or a facsimile of the Great Seal need appear on an uncertificated obligation.
(b) Interest coupons on certificated obligations shall bear the facsimile signature of the State Treasurer. In case any officer whose signature or a facsimile of whose signature shall appear on any bonds or coupons, notes or revenue notes, shall cease to be such officer before the delivery of such obligations, such signature or such facsimile shall nevertheless be valid and sufficient for all purposes as if the officer had remained in office until such delivery.
