Certificate Ceremuga, 2021, notes « Extremely rare error from a sheet that had the LL corner portion folded over during overprinting. Only portions of 4 sheets showing various combinations of overprint errors due to fold overs have been recorded. » Mint with never hinged original gum, some toning and aging to the gum on back, some hinge parts attached to front to prevent perforation splitting; diagonal corner crease through the second stamp, which is not classified as a fault as this is what caused the overprint error (S.G. £13’000+).
