давно не видел ничего настолько крутого. [qsl-карточка от «radio pakistan» — «ریڈیو پاکستان» — выпущена радиостанцией apk-2 в карачи, пакистан, 9 мая 1954 года] A QSL card is a written confirmation of either a two-way radiocommunication between two amateur radio or citizens band stations; a one-way reception of a signal from an AM radio, FM radio, television or shortwave broadcasting station; or the reception of a two-way radiocommunication by a third party listener. A typical QSL card is the same size and made from the same material as a typical postcard, and most are sent through the mail as such. QSL card derived its name from the Q code "QSL". A Q code message can stand for a statement or a question (when the code is followed by a question mark). In this case, 'QSL?' (note the question mark) means "Do you confirm receipt of my transmission?" while 'QSL' (without a question mark) means "I confirm receipt of your transmission." и да, разумеется, я нашел архив с кучей таких карточек.
