THIS IS A VERY NICE EXAMPLE OF A TAGGING ERROR. INSTEAD OF THE NORMAL TAGGING ON BOTH EDGES OF THE STAMP THERE IS ONLY ONE TAGGING BAR ON THE RIGHT. THIS OCCURRED ON SCOTT 593xx THE EIGHT CENT QUEEN ELIZABETH II PRECANCEL DEFINITIVE. THE STAMP WAS ISSUED OCTOBER 17, 1973. THE STAMP IS USED AND IN VERY NICE CONDITION.
