Auction # 2429 ARGENTINA: Special August auction - part II

GJ.313CI, 1910 5P. Centenary of the May Revolution with variety CENTER INVERTED, excellent quality (much better than average; stamps like these, when it was detected that they were misprinted, they were tossed into the trash, and from there they were salvaged by some kind soul, and that is why almost all examples have minor defects such as pressed out creases, etc.). Very rare in this superb quality! With Alberto Solari certificate and signed by Victor Kneitschel on back
