Red Cross Letter Card Used as Airletter in New Zealand

This Red Cross Letter Card, intended for use by PoW's, was sent from a civilian in New Zealand to England. Postmarked TAKAPUNA 18 MR 59.

"Air" was endorsed in front of the "Letter Card" type designation to make an airletter out of the letter card.

This was accepted by the New Zealand postal authorities. The taxation "To pay / 4 d. / Double deficiency postage"  refers to the fact that the airletter rate was 8 d and the "Air" letter card was only franked with a 6 d stamp.
