1965-70 3d. multicoloured Missing value, S.G.335 unlisted, Pierron unlisted,

vertical marginal strip of 6 spanning the sheet with a massive colour shift resulting in the first stamp lacking the face value '3d' and the following five stamps with the face value at the top rather than the foot and the other colour elements shifted by some 7mm; unmounted original gum. A SPECTACULAR ERROR. 



This error is not listed in Stanley Gibbons by reason of the listing policy; neither is it listed by Tom Pierron in 'Modern Great Britain & Commonwealth Missing Colour Errors'
