lot # 162 - Argentina general issues
GJ.403, 1916 5c. Declaration of independence, vertical pair with notable variety: "Large unprinted area in both stamps", spectacular. It is evident that the variety was produced because the pair was partially PRINTED ON GUM, and when it was soaked, that area "vanished", along with the part of the cancel on top of it. NO examples are known of this issue printed on gum, possibly unique, great rarity!
