11.10.1966. Air mail letter probably 5-10 grams to USA. Correct rate: surface rate 60 öre and air mail fee 2x25=50 öre, totally 110 öre. Shortpaid 40 öre. Due mark should in this case have been T 80/60 but incorrectly marked T 100/60 indicating that the whole air mail fee is missing. 100/60 of foreign letter fee 11 c = 18.33 ~19 cents have been charged in USA
