'Provisional' surcharge on 'Arms' issue with OFICIAL overprint. The set of five mint with gum. The print numbers range between 1000 and 5000 and this set includes the 5c on 20c pale rose deemed to be the rarest Paraguayan stamp with Hahn recording that only 1000 were printed and just 292 were sold with the rest apparently destroyed. Odd light gum tone here & there but a very rare set. (SG 180/184)
