VERY FINE. THIS IS THE ONLY RECORDED COVER BEARING A COMBINATION OF THE 3-PESO AND 4-PESO HIGH VALUES. THE ONLY OTHER COVER BEARING MORE THAN ONE DENOMINATION OF THE FIRST ISSUE IS THE EX-CASPARY 2-PESO AND 4-PESO COVER. THIS IS UNDOUBTEDLY THE MOST OUTSTANDING COVER OF BUENOS AIRES, AND, IN A RANKING OF ALL ITEMS, IT IS SECOND ONLY TO THE "IN PESO" TETE-BECHE PAIR.
On this cover the 3p and 4p Barquitos stamps prepay 7 pesos postage. The 5-peso "heavy" rate was required on a letter weighing between 12 and 16 adarmes (16 adarmes is the equivalent of one ounce). One peso was required for each additional 4 adarmes. Therefore, this folded letter weighed between 20 and 24 adarmes (1-1/4 to 1-1/2 ounce), requiring 7 pesos prepayment.
This is without question the most important of only four covers we record with a Barquitos combination, which are: 1) 2p and 4p to Corrientes, ex Caspary; 2) 3p and 4p to Rosario, the cover offered here; 3) 1p Brown and 4r Brown to Uruguay, offered in this sale as lot 73; and 4) 1p Blue and 4r Brown to Buenos Aires, offered in this sale (lot 74). These Barquitos combination frankings are among the highlights of the entire Islander collection.
