In evidence of and as security for funds borrowed, the Commission may issue revenue bonds in its corporate capacity to be payable from the revenues derived from the operation of the institutions or buildings, owned, leased, or operated by or on behalf of the Commission, but the bonds shall in no event constitute an indebtedness of the Commission or a claim against the property of the Commission. Such bonds may be issued in such denominations as may be expedient, and in such amounts and at such rates of interest as the Commission shall deem necessary to provide sufficient funds to pay all the costs of acquiring land, the construction, acquisition, equipping and operation of buildings within the District , including engineering and other expenses. Such bonds shall be executed by the president of the Commission, attested by the secretary thereof and sealed with the Commission's corporate seal. In case either of said officers of the Commission who shall have signed or attested any of such bonds shall have ceased to be such officer before delivery of such bonds, the signature of such officer shall be valid and sufficient to the same effect as if such officer had remained in office at the time of such delivery. The Commission shall furnish the State Comptroller with a record of all bonds issued under this Act.
