Section 61.00. Execution of obligations

a. All obligations, including
  interim bonds, shall be executed in the name of the municipality, school
  district or district corporation by the chief fiscal officer unless  the
  finance  board  shall,  by  resolution, designate a different officer or
  officers to  execute  such  obligations.    Such  execution  may  be  by
  facsimile  signature, in which event the finance board shall provide for
  authentication of such obligation by the manual  countersignature  of  a
  fiscal  agent  or  of  a designated official of the municipality, school
  district or district corporation. Such obligations shall have  the  seal
  or  a  facsimile  seal  of the municipality, school district or district
  corporation impressed or imprinted  thereon.  Such  obligations  may  be
  attested  by  the  facsimile  or  manual  signature of the clerk of such
  municipality, school district or  district  corporation  or  such  other
  official  thereof  as  may  be  designated by the finance board. Coupons
  attached to a bond shall be authenticated by  the  facsimile  or  manual
  signature of the chief fiscal officer unless the finance board shall, by
  resolution,  provide  that  such  coupons  shall be authenticated by the
  facsimile or manual signature of a different officer.
    b. Obligations executed in the manner set forth above by the officials
  designated and referred to above shall be valid and binding  obligations
  when  duly  delivered, notwithstanding the fact that before the delivery
  thereof the persons executing the same shall have ceased to be officials
  or other officials may have been designated to perform such functions.
