1945 (February) censored air letter to Jerusalem, Palestine, written in Hebrew, with a pair of 3As paying the 6As rate. The air letter has been opened and resealed by the censor with P.C. 90 tape that has a â101â in a circle (Type 5) as well as a concentric ring h/s with a number in the centre. A small âFâ seal is also at the foot of the letter. An unusual item from Aden to Palestine, with a scarce censorship.
