International Post Card with Postage Due.
Looks to have been written Oct.13 and sorted Oct.23
July1, 1979 - December 31, 1981: 35 cents for the 1st 20 grams.
Rate seems to have been the same for international letter or post card.
T=18/35 -18˘ short on a 35˘ rate (no return address, so collected in Iseral).
What does the small box say in lower right, and what was collected (in Israeli Sheqel)?
What do the abbreviations in the big box stand for?
E.T.L. - L.P.P. - C/L - S/L
(Many questions

)
Thanks,
Pat
