Above: From Helsinnki 7.5.1948 to England Liverpool, second weight class (21-40g) letter with a clipping from a stationary with 7/6mk orange denomination (stationary card number 94, LaPe) and a 12 /10mk violet M30 definitive lion, together 19mk the correct rate for 1.1.1947 – 30.6.1948.
Seldom there comes the chance to see how an ingenious sender has used a piece from a stationery for paying the postage on a letter. This has been ”illegal” from the point of view of the postal service and what one has in these situations is an item that non in conformity with the postal rate. In the above case we can see that such an item has been delivered and there are no apparent markings of any extra fees or postage dues on the cover. Interesting.
