Auction #1944 ARGENTINA: Splendid selection of "Rivadavias"

GJ.20g, 3rd printing, on VERY thin paper (70 microns), also with 2 shades: In the areas where it was gummed (with dark thick gum), it got dyed to a dark coffee color, and below, where the brush did not get to apply the gum, it has its original orangish dun-red shade, superb, very rare, signed by Victor Kneitschel on back.
