In case any officer whose signature appears upon any bond or
coupon or check or draft, issued pursuant to this Act, ceases to hold his
office before the delivery thereof to the payee, his signature nevertheless
shall be valid and sufficient for all purposes with the same effect as if
he had remained in office until delivery thereof.
