GJ.1, Un Real MC, type 6, used with mute "square of 16 lines" cancel of Corrientes, VF, rare! With Alberto Solari certificate (Image)

GJ.7b, dark blue with DOUBLE IMPRESSION variety, very rare. With a tiny fault of no importance. Very scarce stamp, its real value is much larger than its catalog value (which will be corrected in the next edition) (Image)

Small group of 4 mint without gum stamps + one used with large arch "CORRIENTES" cancel, very fine general quality! (Image)
