Ariz. Rev. Stat. § 9-526
At the election the ballot shall contain the phrases "for the bonds" and "against the bonds." To the right of and opposite each phrase shall be placed a square approximately the size of squares placed opposite the names of candidates on ballots. The voter shall indicate his vote "for the bonds" or "against the bonds" by inserting the mark "x" in the square opposite such phrase. No other question, word or figure need be printed on the ballot. The ballot need not be any particular size, nor need sample ballots be printed, posted or distributed. A number of ballots, exceeding by not less than ten per cent the number of registered voters whose names appear on the precinct register of the precinct, town or city for which printed, shall be printed and furnished each polling place.
