GJ.1, Un Real M.C. type 5, used with mute "rectangle of 16 bars" cancel of Corrientes, very rare. It has a very small thin on back almost insignificant given the beauty of its front, catalog value US$500, good opportunity!
GJ.3, 3c. blue, pair with original gum, type 3 (small defect on back) + type 4 (MNH!), with large top sheet margin, the catalog value of a normal MNH example is US$33, very attractive!
