Auction # 2228 ARGENTINA: Special August auction

FORGERIES: GJ.301 + other values, 1910 Centenary of May Revolution, lot of FORGED die proofs and essays printed on very thin and lightly laid paper (known as Hamburg forgeries), in total 24 pieces mounted on 5 pages of an old collection, interesting to compare and learn, because these forgeries are widely offered online sites, I have even seen them in large lots of important auction houses of USA and Europe.
