Tristan Da Cunha 1966 Churchill Value & Inscription Misplaced

1966 Churchill 1d VALUE & INSCRIPTION MISPLACED (SG 89var). Superb UM example showing value incorrectly placed at left due to shift of gold printing. At it's extremity the affected sheet shows some stamps with value omitted entirely (listed as SG 89a). With normal for comparison. Rare, only 48 possible from the single affected sheet.
