Lot 61661 – 1886 1c blue, part sheet of 61, bottom row disposed sideways

1886 1c blue, part sheet of 61, original gum, showing the bottom row disposed sideways, this being a spectacular characteristic executed in the printing process of some few classic Colombian stamps, with the purpose of using as much space as possible in the available sheets (this feature is also very rarely seen in classic philately worldwide and creates a visually impressive variety), two thin spots, of which only one (tiny) affects one stamp; to our knowledge, two or three complete sheets are recorded and the only one we have seen had no gum; this item, in contrast, possess original gum and has only two hinges; large multiples with the variety are extremely rare.
