I am reminded of the deeply touching letters, cards and messages which so many of you have sent my wife and myself.
我想起了那些感人肺腑的信件,许多人寄给我和我妻子的卡片和消息。

Lettercard
In philately a lettercard or letter card is a postal stationery item consisting of a folded card with a prepaid imprinted stamp. The fact that it is folded over gives the writer twice as much room for the message compared with a postal card. The message is written on the inside and the card is then folded and sealed around the edges. The recipient tears off and discards the perforated selvages to open the card.
