1970-75 Floral Coils 2c Sturt's Desert Rose strip of 7 of which five units are trimmed diagonally and showing error Imperforate', the lower three units showing portions of three normally perforated stamps to the left. Between the fifth and sixth units appear short overlapping colour bars which do not exist on the issued stamps. These imperforate stamps are believed to represent an extra column of stamps that was on the printing plate but was normally trimmed off and discarded. Probably of 'printer's waste' status but nevertheless of considerable technical interest; the BW catalogue illustrates a similar strip of 3. BW 530ce, cat AU$1000
