Vintage Argentina First Day Cover Airmail Envelope

This item is a vintage rectangular paper envelope measuring approximately 6.5 by 4.5 inches. It features a colorful graphic illustration of 'Cataratas del Iguazu' (Iguazu Falls) in the upper left section. The piece serves as a philatelic cover postmarked from Argentina and addressed to 'Alemania Federal' (West Germany), dating it to the Cold War era between 1949 and 1990. The envelope is adorned with four distinct Argentine postage stamps of varying denominations (20 and 50 pesos) and colors (yellow, blue, magenta, and olive). These stamps are tied to the cover by several black circular ink postmarks and wavy line cancellations. Additionally, the envelope features two red 'VIA AEREA' (Air Mail) boxed stamps and vertical red text reading 'CATARATAS del IGUAZU'. The paper shows signs of age-related toning, minor creasing at the corners, and evidence of handling. Typical of postal history items, there are faint signs of adhesive residue or paper lift where a label may have been removed at the bottom, and some slight staining at the edges. The typewriter-written address remains visible despite the heavy cancellation marks. This item represents a piece of South American postal history, demonstrating mid-20th-century printing techniques and international postal transit markings.
