Sovereign 1d. Block of four from the lower left of the Sheet, left vertical pair, one with 'Overprint Omitted', the other mostly omitted. This major error was caused by a paper-fold which took place after the Sheet had been reinforced with paper (in margins on gummed side) and prior to overprinting. The 'missing' surcharge can now be viewed on the gummed-side. A most magnificent and Unique major error piece. [US2] (Start Price = £1,128.00)
