Auction # 2432 WORLDWIDE + ARGENTINA: Special August auction

DEMONETIZATION OF POSTAGE STAMPS: original copy, sent to various post offices, of the resolution of 31/JUL/1957 demonetizing a number of commemorative and definitive stamps, "the first ones due to their temporary nature and limited printing, and the rest, because they do not adjust, individually, to the basic rates of current prices, as they correspond to issues of 1937". It consists of several pages with a long list of stamps that would no longer have postal value, and in the last page there is an interesting line: "...the exchange of the stamps PERFORATED by the shops authorized for that purpose, and the POSTAL SAVINGS BOOKS integrated with stamps demonetized by this decree", excellent quality, very interesting!
