Auction # 2433 ARGENTINA: San Martín (1917), including rarities!!

15/FE/1921 Lanús to Germany, registered cover, it bears a spectacular postage of 1.23P. (including 2x 50c. San Martín with multiple susn watermark, GJ.50), very scarce on used cover!, on back there are transit and arrival marks. By mistake of the postal clerk, this cover overpaid 3c. (the corresponding postage was 1.20P. for a 9-rate registered cover, the additional 3c. were only charged to domestic registered letters!), excellent quality, rare!
