(2) Two diagrams, of suitable size, representing such part of the face of such voting machine as will be in use in the primary or election and accompanied by directions for voting on the machine; and such diagrams shall be posted prominently outside the enclosed space within the polling place; and

(3) A seal for sealing the machine after the polls are closed; an envelope for the return of the keys, if the construction of the voting machine shall permit their separate return; and such other election materials and supplies as may be necessary or as may be required by law.
