Italy 834a

     To mark the state visit of President Giovanni Gronchi to Peru, Argentina and Uruguay in 1961 Italy issued a set of three stamps with a similar map design. The stamp issued for Peru was discovered to have gotten Peru's border with Ecuador wrong. The stamp was withdrawn and reissued in a violet black color.

     Some of the rose-lilac errors were sold of affixed to covers before the order of withdrawal reached them. They were then directed to cover the errors with the corrected version, so there are covers with both the correct and incorrect stamps.
