Israel and Italy
Postage due for "Poste Restante"

Aerogramme (Wiegand no. 22) sent from BET YIZHAQ, Israel (cds 1.9.63) to FLORENCE, Italy (arrival cds on back 4.9.63).

Tax-marked "T" on arrival and a 20 Lire postage due stamp was affixed. 20 Lire was the fee to be paid for general delivery mail ("Poste restante") when it was called for.

The Universal Postal Union (UPU) rules allowed countries to charge a fee for incoming international mail sent to a poste restante (general delivery) address provided those countries also imposed a charge on domestic poste restante mail. [1]
