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 LEFT. THIS OCCURRED ON SCOTT 593A THE TEN CENT QUEEN ELIZABETH II DEFINITIVE. THE STAMP WAS ISSUED SEPTEMBER 1, 1976. THE STAMP IS USED AND IN VERY NICE CONDITION.
