1968 incoming US air mail large postcard taxed postage dues: 15 Feb 1968 postmarked airmailed oversized postcard (Jackie Gleason/Statler Hilton Plaza), sent from MIAMI to Shmuel Federman owner of the Dan Hotel in TEL AVIV & franked 13c - but taxed in the US for short-payment: using the taxe fraction method instituted as of 1 Jan 1966 by the Universal Postal Union's (UPU) Vienna convention, of the sending postal administration indicating the amount owed as twice the deficiency in the numerator and the country's base letter surface postage rate in the denominator - here the cover was deficient 12c for the 13c rate, and charged 24c as the tax.
In Israel this ratio was multiplied by the country's period base letter surface postage rate of 30 agorot, yielding a calculated postage dues tax amount of 55ag, levied on 20 Feb at TEL AVIV-6 (Head Post Office) using a 0.55L 1965/67 1st Town Emblems stamp (Ba #366); front-stamped & backstamped 21 Feb TEL AVIV-87 (Nordau Street branch office) delivery. The manuscript number ("3219") on the front was the hotel's post office box number to which tax mail like this was accumulated; the notation "copied 8/3" refers to the date on which a notice was issued to the addressee to come & pay for the letter.
